love it but i have one issue so far
 

i want carth to just use critical strike because he sits in the back and the defense penalty doesn't matter... but he keeps switching back to auto attack! meanwhile.. when i switch away from my main character to make carth use critical strike... then my main character (who i actually want to auto attack) keeps switching to fury and lowering his defense!

is there any way i can just make my main character ONLY auto attack always, and carth/other characters ONLY use abilities always?

I don't think there is anyway of making them do it automatically. However, you can do it manually by pausing and lining up their attacks individually.
