Rogues and hunters during the killing of mages/kiting phase really shouldn't happen much. Druids and priests could throw HoTs on them while they're killing mages, but the key is to not pull aggro on legionaires or dragons onto you, since you'll then be quickly dead, which is bad.

During the actual fight with Razorgore, they need to take care of themselves. There's not enough healer mana around to keep themselves, tanks and DPS alive. Razorgore's attacks are easy to LoS and bandage or pot or whatever they need to do. You know more about healing than I do, so if you can figure out a way to not pull aggro in the first phase and not run out of mana in the second phase, by all means toss them a heal. It shouldn't be a priority, though.

We have the same guy do all of the controlling. I don't know if that's the best way to do it, but he runs in and just keeps picking up Razorgore, as far as I know. I'm usually too busy killing mages to pay much attention to who is doing the MC, so I could be wrong. I'm almost sure our strategist and raid leader just takes care of it.
