I'm so glad you figured out the Jade strat! I had a lot of fun making her as broken as possible (she's seriously under-used in Collide, and one of my favourite characters, so I felt justified in over-correcting haha). The main fights are supposed to be easier than the Cond, as the Cond would be controlling 5 People at once, and output would naturally suffer, as opposed to her full attention in her actual fight.
Could you elaborate on which characters you found lacking? We tried to give each character a unique playstyle, but its very likely we flubbed a couple, so feedback will always be welcome
