Sure, I'll bump this for memories.
We used to bring the buffbots to MC and BWL and hate ourselves for it. By the time pallies got the longer buffs, all of our pallies had rolled something more useful, so they'd bring the pally to the raid entrance, buff everyone, and then swap to their rogue or whatever. The one question we'd ask pally apps was "Do you have a macro that makes you faster at buffing Kings?"
But hey, with the Legacy system, Troopallies will be able to buff all buffs!
