OP, why would that make you a horrible person? I get that DD classes are quite literally the bad boys of MMOs, but I find no difference in someone who chooses to main DPS over a healer or tank who chooses to main those roles. A skilled, experienced, and knowledgeable DD brings a lot to the table.

I main healer, but I enjoy playing DD classes as well. Especially DRG. I do enjoy seeing the big numbers, but it's not about that. I think it's more about showing the community that a DD can show they care as much about their group as they do getting a clear. I can't help but bring my healing mentality no matter what role I play.

Just be you. If that is a DD then be the best you can be.
