Well, sometimes I do pull extra stuff on me as Scholar when I know I can take it to speed things up (like those two tonberries near flan minion). That said, I never expect the tank to grab hate on those mobs, and "tank" them myself.

It works just fine, and helps get some extra speed when the group in undergeared (yesterday I did that when I queued up with a full iLv55< group. No one complained, no one died, we cut a few minutes without overwhelming the tank, everyone wins).
