Provoke is most likely going to be used in a 1 party situation, in that case it will work as top enmity plus one, however in fates its pretty much a gamble how much agro your going to grab. There is a cap to aggro on what your going to pull from it. Many other players in fates will just drive the enmity just so sky high getting aggro from them while they are alive is impossible. I wouldn't even bother provoking in a fate situation or where 2 parties are involved. And as for bards like that, I recommend staying clear and letting the fools die and let somebody smart aggro that monster... like a actual tank class.
