I can get behind wanting to be top threat constantly, and can see why it'd make you wary of letting a ranged class pull. Think it goes back to the whole "managing aggro is a team effort" thing. As long as everyone knows what's happening, it can be pretty smooth. Oddly, none of the pulls you list are ones where I normally do this. :p Normally, I'll wind up pulling the last two Succubi in AK, and maybe the Dullahan pat along the walkway. Really, I feel it's more useful for places where Provoke just still isn't enough range. Like, I usually feel a little iffy pulling the third Succubus in AK without getting the group, and I'm fairly certain BRD has more range than your Provoke.
