"You pull, you tank" is a bad mentality

[Malthir]

Maybe you should define "not letting tanks do their job".
Because if you pull a mob to the tank and he stops hitting the AoE buttons, it's the tank who refuses to do their job.
And if you're not required to tank, why does it bother you so much that you're not tanking?

So you just ignoring what I said about CD's. We have moves that make use take less damage we need to use or die. If I start a pull I'm popping some of these, if it's a big pull I wait till all mobs are together, before pressing CD's if it's a small one I use it as soon as I've got the mobs were I want them. If I've press my CD's and then all of a sudden another pack of mobs is brought into the fight, I'm getting shafted, because the DPS decided they were bored/wanted to get a purple colour for this dungeon.

There are many reasons as to why the tank is pulling smaller packs, by all means ask is there a reason, and maybe suggest you could gather them up etc. However the fact remains, aggro is the tanks responsibility their for pulling is their responsibility and the decision of how many mobs are in this fight, is the tanks to make. If you don't like that when you pull as a DPS, you're rolling the dice on if I feel like taking aggro from you, but you're literally now the bottom of my priority list. Staying alive is number 1 and if that means I watch 3 mobs smash you teeth in for the next 30s while I waste of CD's then that's your fault.
