I know i'm a little late on this one but, fight or flight the gladiator ability sounds really weird to me. shouldn't it be called adrenaline?

Fight or flight, to me, sounds like it should increase attack and evasion or movement speed or something, but it only increases damage dealt. So I thought about why it's called fight or flight and came to the fight or flight response which is a reaction we have when we are effected by adrenaline.
