Stop crying please. None of these points are valid. Enmity is fine the way it is.. Just cause u dont know how to hate manage as a mage is no ones fault. I dont have that issue.

Gear damage is fine.. get crafting.. cost less
MP cost is fine.. learntoMPmanage.com coordinate with other mages in the party
