Personally, i like the current way how MNK plays. My only concern is just the Anatman Skill, which seems to be just a bad gimmick Skill attempt.
I think it would be a more interesting Skill, if it was instead, a 50 Poteny HoT that doubles its potency after every 5sec (up to 25 or 30sec) as long as you stand still and keep it channeled, but on a long Cooldown, like 3-5Min.
