Solidstate requested the Razorgore strategy we used, so here it is. We use a pretty normal strategy.
Hunters, mages, warlocks, rogues are divided into 4 DPS groups, one in each corner of the room. They kill orc mages as they appear. They also crowd control any legionaires if they can (sheeps, stuns, traps, succubi).
We have two warriors (with speed boots) kite the dragonkin and legionaires in a Figure 8 around the room, using both platforms. They run up one ramp, and then jump off the middle in order to buy some additional time, as the mobs go back down the ramp and around. They are spamming Demo Shout and taunting any new mobs that appear.
The remaining warriors pick up loose dragonkin and legionaires and bring them to the main kiters. We usually had a warrior follow each of the main kiters, picking up any missed mobs.
The druids' primary job is to sleep any loose dragonkin until a kiting warrior picks them up. They also do a little healing.
The paladins and priests are the healers, with the priests trying to keep their aggro down as much as possible. The paladins also guard the ramps to the controller, stunning and engaging any mobs attempting to get to the controller.
There are two or three controllers who rotate controlling Razorgore and popping eggs. We don't let the orcs/dragonkin attack Razorgore. It makes the last phase a bit harder, as Razorgore is at full health, but that's just a ranged tank-and-spank fight.
Realistically, it's all about the kite and aggro management. If you have one priest who does much more healing than the other priests, she will pull aggro and mobs will swarm the center. Paladin heals are lower aggro, so priests should try to defer to the paladins as much as possible, use HoTs, small heals, etc.
That's the strategy we used last night. Of course, it does take practice. We took about five tries, progressively getting better each time, and tweaking the strategy each time (for some reason, our kiters weren't doing the full Figure 8 for the first few attempts).
Another strategy I've seen is to have the main kiter be the first Razorgore controller, and to use Razorgore's Shadow Volley ability right before the control timer expires. That transfers all the aggro to the main kiter, giving her an edge as she starts the kite.
