I have no problems with any of the current directors but for a while now I've been thinking it would be a good idea if Funimation also used some "new blood". 
I heard Funimation holds an open casting audition once a year (the chance to basically have your contact info listed and maybe get called in for work in the future).
This is the basically the only opportunity for any aspiring voice actors & voice actresses or stage actors & stage actresses looking to move up from theater, to get their foot through the door into the anime voice-over industry (in Texas).
Most of the current talent pool who are regularly cast got into anime either through a friend who already worked at Funimation (early years) or got lucky at a convenient time.
Those who get selected at the open audition (and eventually get called for work) start out voicing background or minor characters (additional voices) and eventually move up to voicing guest roles, recurring roles and maybe main roles.
One problem is that some talented voice artists never get the opportunity to move up from "additional voices" and guest roles because the voice directors prefer to cast the same people.
The voice directors would rather cast someone who's range and voice they're familiar with instead of a newbie who they don't really know.
A lot of people who work at Funimation are also good friends in real life. That's great and all but the downside to this is that sometimes the voice director miscasts their friend for a role and their favoritism can ruin a dub. 
You only need to look at some voice director's credits and see the main cast. You start to see patterns and it becomes very clear which voice actors & voice actresses are overused. 
The directors can try and defend themselves saying that they keep their personal relations apart from their work, but the fact is whether they want to admit it or not, working with friends can affect your decisions and more often than not it usually does.
Another thing worth noting is that while everyone who works at Funimation has heard of each other, not everybody has actually worked with each other or even met each other.
Having some new voice directors would "even the playing field". They don't know everybody so they have less pre-existing favoritism during auditions for new shows.
New directors means more opportunities to have new people in lead roles (main & supporting characters), less type-casting, and a chance to have fresh dubs with voices that don't remind fans of "that's the exact same voice from that show". 
I wouldn't mind seeing these people directing new dubs in the future:
(they all have experience but I guess no opportunities with Funimation at the moment) 
Chris Ayres (Night Raid 1931, The Wallflower, Xenosaga, Nerima Daikon Brothers)
Patrick Seitz (Girls Bravo, Tales of Phantasia, Kamichu, Monster)
Christine Auten (Utawarerumono, Best Student Council, Moonlight Mile, Pani Poni Dash)
Sonny Strait (several Lupin III titles, Galaxy Railways)
Justin Cook (Yu Yu Hakusho, Fruits Basket, Dragon Ball, Kiddy Grade)
Matt Greenfield (Tears to Tiara, Blue Drop, Coicent, Five Numbers, Gantz, Neon Genesis Evangelion, Golden Boy)
Of course some haven't directed in quite a while (e.g. Strait & Auten) or some have other duties (e.g. Justin Cook is a Director of Production; stepped into that role a while ago at the expense of not having time to direct dubs anymore or even voice act as often)
Well those are my thoughts. Not sure if anybody else feels the same way but if you do let your voice be heard! 
To note, Matt Greenfield does work with Sentai, so I'd kind of find that unlikely. I don't really see it being an issue, sadly enough some people are just best suited to being extras. It doesn't mean they don't do other things though. It does help that a director knows what someone can do, that is hardly uncommon in any job field. If someone needed an engineer, should they ask some random person they know has done simpler stuff, or someone they know that can do an awesome job?
Same thing here. It is referred to as scouting. They see a role, and can picture in their mind what they are looking for and go for that. I am sure more than once a director had to "settle" with something because there was no alternative even after constant auditions. It is not like the directors are favoring people, it is their job to make the best production possible. Would I like some more variety? Sure, but not at the cost of a good production.
Being wrong is not a democracy!
This is pretty much how I feel as well.
I feel exactly the same as the poster of this article. I want much wider cast of actors and actresses because some of them dont have the right voice for many characters. Sure, they got the skill or approach sometimes but not the right VOICE and voice pitch at that. Playing little girls some dont know how, and i'd like to see real teenage talents playing their parts for girls would be more realistic, feel easier on the ears and so much more sweeter seeing the acting on screen matching the voice of the characters.
Seeing an actor playing a younger character is fine by me but not to the detrimental effect of scrapping the dub and the stories for me. If the industry is to grow they need hundreds more actors for anime and a school or educational institution with learning environment JUST FOR ANIME IN NORTH AMERICA. Much like video games now has university course for game design since 2009, this needs to happen to expand the growth potential of the studios, production companies and the fan following them.
Much like they would need to establish an ANIME actors council and production councils tagging with VIZ, FUNIMATION, SENTAI and any major labels.
Achievements are the making of mankind, and so, we chose to move forward! ;p
Well the biggest thing for me is "additional voices" get bigger roles/ If not main character roles giving them the chance to grow like DBZ cast who were pretty ify it the starts of their careers.
The difference between Gaming and anime, however, is that Gaming is WAY bigger than anime in the American market and therefore MAKES more money for the company; whereas people involved in the process of bringing dubbed anime to America gets paid beans compared to other jobs they could be doing (ESPECIALLY the actors). This is why most of the employees at companies such as FUNi have multiple jobs within that company rather than just one. The money it would take to make an institution or even a small school dedicated to teaching only Anime voice acting is WAY more than what the anime industry can handle at its current state (and the fact that the majority of anime "fans" using illegal downloads as their source of anime doesn't help either since that's making no money for the company, but that's a whole other argument altogether).
I'm not sure how this would work out as it could go either way (either relatively well or horribly wrong), but I think it would be a really complicated thing to set up seeing as how the only voice actors who actually "work" for those companies are the ones who already have other jobs within those companies like ADR scripting, directing, licensing, etc... Voice Acting (and any kind of acting for that matter) is a freelance business and not a secure job with any real allegiance to any one company.
As for getting new directors, I agree that it does get a little bit tiresome recognizing the same voices in multiple shows, but you have to think of it from the directors perspective. They hire people that they know that they can trust to do a great job with what they're given, and when it comes to newcomers it's really risky for the company in general and not just something as shallow as directors not being familiar with new actors' voices. Because studio time costs an arm and a leg, the directors have to know that the person they bring in for the job can get there efficiently, on time, and get their work done professionally so they don't have to spend more money by staying in the studio longer than they have to. Yes, there are newcomers in the industry that may have EXACTLY the voice they're looking for and they might even be one of the most punctual and trustworthy people to have within a project in terms of everything I mentioned earlier, but if the director doesn't know that newcomer whatsoever and only has an audition to go off of, then they wouldn't know if the person is reliable or not (now I'm pretty much just rambling so I'll move on).
Anyway, I don't know the entire list of FUNi's directors, but I do know that I love what they've been coming out with over the past few years of watching their shows (even if I do hear the same voices a lot).
That's a personal opinion thing - they can never satisfy everyone.
Problem with using kids is you have to schedule around their schooling, and they can't work as late or for as long etc.
Why? Do you know many titles which have hundreds of non-background characters? Where are all these people going to find work?
Signature? What signature?
True but his wife Tiffany Grant has worked for Funimation before so all it takes is a meet and greet with one of the line producers.
Even though Matt Greenfield does work for Sentai it seems to be only occasionally at the moment. Steven Foster still directs 98% of all their dubs.

And almost all of his dubs are awful like this one.
Personally I think Funi is fine with their current directors but I guess it would'nt hurt to look for some new blood, or use some others every now & then. Personally i'm more interested in funi expanding the variety in their voice casts for the shows they acquire, seems like the same half dozen people are in pretty much everything these days, lol.
LET ME PLAY FOR YOU, THE SONG OF MY PEOPLE!!!
I'd definitely love to see some of these people direct some Funimation dubs.
If Funimation ever gets off their ass (or TMS stops being one) maybe Sonny Strait can direct the Lupin III vs. Detective Conan TV Special
Night Raid 1931 is probably one of the best dubs I've heard this year and Chris Ayres did a fantastic job. I saw a video on youtube of one of his Q&A panels at a convention and apparently he said he managed to complete this short amount of time due to a scheduling mix-up. Sounds like he almost worked himself to death but the result IMO was well worth it.
I'd like to see Justin Cook in the director's chair again, he directed some great dubs.
But I am glad he stepped into the role of "head producer" when he did. We don't want more Barry Watsons (how's Illumitoon doing?
)
I haven't watched Monster yet but I've only heard good things. I have seen Girls Bravo and I think Patrick Seitz did a great job with the casting and it was a very entertaining dub.
Utawarerumono is probably one of the most underrated shows I've ever watched. If Christine Auten helped direct it, that women needs to do more directing!
Gantz and Golden Boy I both watched recently. Great shows and I'm angry I didn't watch sooner. Gantz in particular was one of the most enjoyable dubs I've ever seen (period!)
Matt Greenfield should definitely direct more stuff. It was a nice surprise to see his name attached to Five Numbers and Coicent.
