DPS who pull mobs

[AnotherPerson]

No pulling mods ahead of the tank is griefing. You won't win that one with a GM. You can pretend to be big and bad though. We see this on forums all the time but it rarely happens in game.

The tank's job is 2 parts:
One is to hold aggro and the other is to reduce incoming damage to the party to make it easier for the healer to heal by flattening out the damage curve - may it be by mitigating damage or positioning yourself away from the party so they don't get hit by excess AoE and cleaves, or interrupting enemy casts.

If someone gets aggro and the tank is not taking that mob's aggro when they bring the mob to them, then they clearly failed their job as a tank and burdened their healer more since the healer now have to heal more party members, not to mention DPS and healers have lower defense values & HP values.

From the healer's perspective, the tank's griefing. Tanks have easy ways to take the aggro back since their tank stance generates far more aggro per hit than a DPS or healer would, so it would only be griefing if they purposely ignored the mobs after they were delivered to them because they would have to stop using their AoE skills to take that aggro back - and in which case, they are purposely doing single target attacks which means their overall DPS also drops - Again putting more pressure on the healer since all mobs are now dying at a slower pace with the chance that the DPS or healer can take aggro back since the tank stop generating aggro over the initial mobs. If the DPS ends up taking aggro back on all mobs, there's a high chance one of them will die, the healer will have to heal both targets - increasing their overall aggro generation and also makes them susceptible to taking damage via aggro too.

And all that damage is more difficult to mitigate since DPS and Healers aren't tanks with a lot of mitigation cooldowns. So yes, the tank has utterly failed their job and is griefing if they cannot hold aggro.

Now if the tank did hold aggro, used their mitigations properly, and still wiped? Then it's not the tank's fault. They held the aggro as much as they could. That's the fault of the person who pulled more. However, if the tank doesn't take aggro at all? That wipe is on the tank for not even trying. This is a very important distinction to make.
