I found only the yeti and gnoll commanders (basically leader mobs) mobs atk you, other mobs don't, only the bosses. And if you spear, boss atk, run away from boss so he doesn't hit you, wait until they stop, they will stop atking you even when u spear / use smash.
Oh, and out of curiosity, is there a way to unbind those pre-existing binds? The way it is atm, I have perma binded my hfs, so when I press a button it does two commands (one from my binds, the other from Ramza's).
