This is a little bit of QQ then. I play on my deathknight tank and ofc, as with any tank you are expecting to make the majority of the pulls. You rarely actually announce you're making pulls, you just do it, and if you don't do it people say "Come on tank" or more simply "go".
I'm fine with this.
Yet certain rare portions of dungeons can be pulled by DPS. The three that spring to mind are Cookie in Deadmines, Siamat the last boss of Lost City of Tolvir, and the trash pull in new ZG where when you pull the mobs immediately start turning into evil snakes. And these situations don't require a tank pull. In fact Siamar MASSIVELY benefits from a dps pulling, as you can knock about 10% of his health off before he puts his shield up if you're fast. A tank pull is detrimental to that boss. Cookie can be pulled by anyone but again it is more beneficial for a dps to pull as they can start DPSing immediately. And the mobs in ZG, again, the DPS just stand around waiting for a tank to pull even though the mobs are supposed to be dead before they even turn tankable.
Ok this may seem silly to some but basically if a pull benefits from the DPS pulling why do all DPS at these points stand around staring at the mobs saying "go tank". They don't understand their own job. I am happy to do my job and pull when it's required of me but if a pull is BETTER when made by a dps why do no dps actually take up this task and instead stand still waiting for the tank to do it?
