.........i dont even touch them so i dont even know anything about them, and there is a clear division between normal characters and ex/gold chars.....

arcade on maniac seemed easier than ac and ac+, the AI seems to slashback alot less, also they tend to whiff alot of shit when they try for okizeme like anji would throw out butterfly way too early and try to fuujin sometimes, sol seems to spam VV alot less often but still does the good old gunflame frc>bandit bringer alot, boss ino's still boss ino but her AI doesnt seem to be able to combo into her super reliably
