While i completely agree that DPS need to learn to focus and control their TPS. A part of tanking gameplay, and part of the fun of tanking is retrieving the odd 'one that got away'.

To this end, in my opinion Provoke, is possibly the worst 'taunt' like ability i have ever seen in 10 years of MMO tanking. Its not a taunt, and its reliability largely depends on the relative difference of your GCD to the player that has pulled it.

Again it could be argued that this is down to the lack of skill of the person that has pulled the agro in knowing when to stop unloading, however as a tank it makes you feel quiet useless... by all means leave it on a long CD ( which it already is ) as when to use a taunt should be strategic, but i would really like to see it give the target a focus for N seconds similar at least giving you time to rebuild some threat head room.
