at some points in the game success rate is really f-ck up, if that happend you can miss every single attack at a boss or a low lvl char in pvp can hit you even if he should not
I'm not talking about completely altering it i just think that if you have 2k dodge and another person have 1k hit rate he shouldn't be able to hit you (or 300 hit rate at this matter) if you have over 1k higher state it should garntee something
