Healer most of the time. In TF2 I'd play the Medic, in Project Reality I play medic, in Battlefield I play medic. In Overwatch I pretty much only play Ana, I'll only DPS or tank if we need such a class. I dread playing as tank though, I hate the clunkiness of it, so I'll mainly stick to Ana and Tracer/Pharah. I prefer keeping teammates alive rather than trying to get POTG.
