Tanks can't always pull wall to wall, why is that so hard to understand? There are a few factors that determine how much a tank can pull, like the gear of the healer and the DPS (I'm pretty sure I don't even need to elaborate on this point, it's common sense), plus the tank's knowledge of the dungeon. I've been in dungeons where I couldn't rely on the healer to support me and yet they insisted on doing mass pulls, with DPS trying to grab more mobs for me. The fact that this kind of behaviour is encouraged is one of the reasons why you don't see many tanks in the game anymore. I see people in this thread saying that every player's needs and fun are in equal consideration, then if so, the tank is also due the same respect in kind.
