Arena DLC is pretty much assured, I imagine. Because yeah, it was horrible. I would at least expect some ultra-monster to be in there or to fight through five or six battles non-stop like you did in VII. Instead you do one fight against relatively easy used-to-be-a-boss opposition at best, piece of cake cannon fodder at worst.

Maybe harder fights unlock near the end of the game, but when you only have so many days to do everything I don't think people should be expected to check the arena on that regular a basis unless it has a full week's schedule to hand.
