I assume that anti-cheat checks (for example, AAC fightspeed) would need to be disabled for OldCombat to function without constant interrupts.
Most anti-cheat plugins will detect fast fighting (meaning that they expect new combat parameters) and block it. I was suggesting that the assumption should be verified by testing.
