The stats may not look great, especially the damage and Regen, but believe me, both are much better in game. With golf gear and purple jewelry, I would easily hit 12k frags and who knows how hard my curse and endless fury would hit for. I never seem to run out of magic, even with sword and shield, but if my magic gets too bad, I have dark exchange. I really enjoy this build, and I do well with it. Especially in battlegrounds.

The Ultimate depends on you, I've only tried Destro Ult and Atro, and I like them both. Can't wait to try dawnbreaker for that cheap and quick 4-6k to add to my burst.
