Sounds like the same group of people that expected Healers to DPS because.... of reasons?

If the dungeon is finished with no one dying and you never loose hate then a tank has done there job, to hell with those thinking anything. Espeshelly dpsers who will never tank because they dont get there number high -laughs-

I am a full time Main tank and Healer. I will block anyone that starts complaining saying im not doing enough dps on either. They can go find another group and go back waiting in there long ass Q
