Some annoying behaviors and perceptions

[Sigiria]

So running a marathon in corridors pretending you are Lara Croft is the right thing? Maybe you didn't understand what I'm saying and for what situations I'm talking about. Tank CAN'T pull the mobs back if you are running away. It's just not possible. You can move to dodge AoEs but running down the hallways all the way to another room is just plain stupid. Yes you can blame the tank if he is not taking the mobs back but running away means the tank CAN'T take aggro back no matter what. It's just the wrong thing to do.

Maybe you didn't understand what he was saying, bringing back the mob to the tank as a healer or dps because you managed to get the aggro is actually less dangerous.
Seen a few tanks running after a mob they lost pulling the pack out of dps aoe, toward ranged dps and healer, get them cleaved real good, and lose the other mobs while trying to get the aggro on that one mob that ran away.
If the guy that got the aggro just come close enough to the tank's aggro aoe none of this should happen
