I wouldn't mind if enmity mechanism is modified to add the aggro thresholds as in World of Warcraft. It would be a vast quality of life improvement for tanks.

At the moment Provoke is virtually useless without a follow up. That means it takes at least 1 GCD to use provoke properly. With a lot of targets who stop to cast AoE or just plain get stuck for a second or two, it takes even more GCDs to get a hold of the target. Either that, or the tank has to move and break formation. With a aggro threshold (e.g. 110% for melee, 130% for ranged) a single provoke should last long enough for the target to finally approach tanking range.

Of course, I'm not saying that the current way of "DDs need to L2P" is bad. I don't mind that. I'm just very tired of teaching all the DDers how to play. orz
