Provoke is a fantastic pulling tool, for times when there are wanderers that you want to tag out from the group but know that getting too close to lob might end up with 4-5 mobs on you instead of the 1-2 you want to pull.

And honestly you gotta have pretty bad reaction time to need provoke in most fights, I probably use it 2-3 times per dungeon run, most of which are for pulling pats.
