I feel like the miss stuff is fine - it's just an abstraction anyway.
I'd rather have the team create animations for new enemy types than animate block animations for existing enemies/players.
Nobody said they have to drop every other animation to make a block animation, just that it would be nice to have in the finished game. If they decide to add block/parry animations they can simply add it to the list of animations to work on for enemies, and as they create animations for enemies they're still working on they can just slip that in with them as well, and then go back and slip it into the already completed ones after they finish animating the others.
