AoE tanking or tanking for AoE

There's been a recent thread where it's been suggested that paladin AoE tanking it too good which leads to the other tanking classes feeling unloved and clamouring for buffs.

While it's true that the tools available to a paladin tank are well suited for generating threat on a number of bad guys all at once, especially if they're undead. In this expansion all tanks were given a method of generating threat on a number of mobs all at once helping to the removal of crowd control from all but the toughest heroic instances.

I do have to wonder now though if the reason for the current upset about what can be done is the resurgence of running heroics for the daily brace of frost badges. Given that the base level of gear available is now well in excess of what was required when level 80 characters first started running those instances and every dps character has some kind of AoE spell. Is it more a case that all tanks can't necessarily stop a stray mob from running off to smack the aggro monkey when they do all out massive AoE damage when all they need to do it stop the bad guys running after the healer.

However if the DPS went point and shoot on individual mobs using an assist macro the tanks shouldn't have as many issues, and threat indicators such as Omen or Threat Plates will mean you've got a better idea of what to do.

Now is this the fault of the class designers, not really, it's more a 'creative use of game mechanics' for something that we generally now massively out-gear and see as more of a chore rather than the challenge of say the new raid zone.

Rather than trying to homogenise the tanks and the type of threat output they produce it would be nice to see the dps (of which I am at times) adjusting what they do to make it easier for the tank to do what they do.
