Eh, its not perfect, it seems like the AI doesn't understand "meme" or unconventional builds, such as staff medic, palm alchemist, offensive dancer, etc.
I told it about a party i'm playing EO2U with one beast, two medics and two alchemists and the AI didn't understand it and didn't know how to make it work, trying to put everyone in the back row and being confused overall, but at least it tried to implement the staff skills somehow to not repeat with the other medic. The second alchemist sucks tho

It will probably try something if I tell it "you can't have 4 characters in the back row", but I think I've played enough with this for now
