You can't heal or tank your way to content completion, but you sure can DPS your way.
So you are saying tanking is easy because the tank never has to rez the tank, right?Hardest role by far is Tank!
DPS: all you have to do is bring boss down and stay alive!
Heals: try and keep everyone alive while taking down boss. if heals is down dps can revive.
Tank: if they go down well *** your screwed heals takes agro, dps trys to revive tank then dps is not getting heals because heals is trying to keep themselves alive and the rest of this fight is going to go? I don't need to say.
