Did you play test Squadron Command Missions at all?
So I figured I'd start with Halitali, a nice easy dungeon to figure out how the squad works...
Turns out they work like morons. On the second boss the entire squadron refused to fight anything but the damage immune Guivre, unless I hit engage for every single lightning elemental during the add phase. Fun times, but hey at least they seemed to be immune to the lightning infused puddle on the floor.
Fast forward to the final boss and again, the genius squadmates refuse to fight the fire elementals, instead preferring to stand in a big pool of fire to do zero damage to the boss. But this time they aren't immune to the fire and take damage faster than I can heal it.
No chance I can get them to kill the elements and the Damantus so it becomes a nice fun game of spam heals until they die one by one.
Seriously, did you play test this at all?
