Mages were already nerfed regarding area damage, since we had to pull non linked enemies one by one to get xp. No one would blast multiples enemies and get no xp. The reality is the mp would go down easily before, I can't even imagine a heal cost 5x worse will do. Now when I play my warrior class, I can heal once and zeroe the mp. Awesome! I wonder why they didn't mention the nerf before teasing us with new content while the gameplay got even worse...
