They better because they haven't covered everything. First the original manga is still ongoing. Then second manga is ongoing and if you ever watched OVA there is still at least some characters they have not introduced yet as well covering the conflict with Turan. That is at least worth another 12 episodes. To make this series truly epic they need to continue until they at least reach the 3 year time skip to a older Arslan. The story is rich enough they could go all the way to 100 plus episodes.
While I understand that they can have technical difficulties, it would be appreciated if they at least posted a note on the show's page. That way we would know if its just going to be late or not airing. A simple "This show will be broadcasted next week at …" or a "We are having minor difficulties the latest episode will be up as soon as possible."
