This game has the most useless magic system I've ever struggled with. The only spell I ever used was heal. Any time I tried using magic (and I tried) during a battle, it would end before my mouse brought the spell over my character. It'd be better with hotkeys or simple 1-click casting, especially since there's only one target you can ever cast on, which is whatever you're whacking with your sword(s).
Anyone who says this is a WoW copy needs to learn some mythology/history. Almost nothing in WoW is original. They've stolen everything from somewhere else, Lord of the Rings or Warhammer for instance.
