If you made to the endgame as a tank and made it through all the other dungeons with little problem then it probably isn't all you. DPS and healer need to learn to control hate just as much as you. There are very clear indicators to the left of the screen indicating your level of hate. The icons go: Red, orange, yellow, green. Red means YOU have hate. Orange means your about to get hate. Yellow means you picked up a little hate. And green means you have no hate. Those are important things to be aware of and everyone should be adjusting their tactics accordingly to their role.
