A good reason to pull with provoke, too, is that it's oGCD. There are some times where if I'm in motion for shield lob my GCD isn't up in time for me to actually gain thread on the pull I just alerted, and thus when the DPS goes "IT'S RED, IT NEEDS TO BE DEAD" or the healer decides to do... anything at all. Then *I* am the one chasing the pull.

(And if you don't think this happens often enough, you have not had the kind of rowdy groups I've met.)

No one's ever told me not to use Provoke, though. Ever.
