Why do attack variation, direct hit and critical hits exist at all? They could make every skill and every ability and every auto guarantee the highest roll and a direct crit. It would make everything that little bit more boring, but it would be extremely easy to balance. Or better yet they could replace everything with an "attack" button, that way everyone would be doing their rotation correctly and there'd be no unexpected paradox magi, dragon kick monks or yukikaze samurais. I just don't buy making everything uninteresting for the sake of balance being remotely good in the long or short term. At 90 Warrior is currently the fifth most miserable job to play, and I'd like it to be better.
