A guy I know at my local comic shop told me today that a warrior is the worst tank in the game. He said they were just supposed to be damage dealers.
It got to the point that he said he would never run missions or dungeons with him if I did a tank role.

Is this true? I started my character under the impression that I'd be tanking.
I've been tanking and thought I'd been doing good. But I haven't gotten to Warrior yet.

Thoughts or opinions?
