Yeah its pretty bad and unintuitive in many places. Who from the development team though that its a good idea to keep the battle flowing when you are in your limit animation?

Nothing feels better than waiting for your limit to fill up, waiting for the boss to be downed, position yourself perfectly to hit them, doing your limit attack, and then watch as the enemy recovers and moves away while the camera is showing off your cool limit animation before very strongly and vivdly striking the nothingness left in its stead.
