I generally lean towards tanky roles. It started in WoW in the early days when comparatively few people were playing Warriors/Paladins/etc, so I rolled one up and got TONS of positive feedback from other players. Lots of people appreciate healers, damage-dealers, and such. But people LOVE a good tank. So I stuck with the role even after leaving WoW behind. City of Heroes, TF2, didn't matter. Always the tank, or healer. Whichever was in demand.
