Dark Knight.

I have a myriad of reasons why, from playstyle, aesthetic (except for the godawful armor), to just liking big weapons. But I think perhaps the most important thing for me, is that I am first and foremost, a guardian of my friends. I've always played tank roles in MMOs because the role matches how I act, I always try to keep my friends' and family's best interests at heart. However, I'm not one to stand idle when I am unneeded in a combat situation in RPGs, if I am not tanking, I want to be slaying the threats. I take a much more direct approach to defense, if I'm not a tank, I am there to slaughter my enemies, not heal my allies.
