At our last BWL raid, my guild had a lot of problems with Razorgore. We've been 1-shotting him for months using the kiting method, but more a lot mages than usual were spawning, and we kept wiping.
Are there any write-ups on the dps method? It'd also be helpful to know how much dps is needed in order to be successful. I'm not sure whether it'd be feasible for us. I think we have good dps (we usually get Vael below 20% before MT dies), but it's highly skewed toward 3 or 4 rogues, 1 fury warrior, and 1 hunter. Also, a lot of our tanks have trouble holding aggro on more than one target (stage 1 of Nef is a major pain for us), so I could see a couple of corners getting overwhelmed.
Without meaning to sound flippant, but.... Kill Everything That Isn't a Dragon the instant it spawns
It's really that easy.. as long as you have the dps, which you should you should be more than capable of assisting down mages first then any spare legionaires. Tanking is a bit of a non issue as their are all stunnable and don't live long enough to trouble rogues tanking them etc, hell I bugger off from my corner at about 8 Eggs to control Razor and leave my corner with no tank. Once you have control over the spawns and a bit of coordination, it's far easy and more forgiving that kiting.
1. one warrior at each platform doing figure of 8 kiting around that single platform and keeping agro on the kins with dem shout and picking them up on the run with sunder as they run up the platform when they spawn. Druids help by sleeping one kin each. You'll also need 2 healers standing on the corners on top of the platform to heal the kiting warriors.
2. Now as far as DPS goes, it is very easy. Notice that there is 4 corners in the room, but each corner actually has 2 possible spawn points right next to each other, so total of 8 spawn points in the room. We just assign one group per spawn point and it becomes one of the easiest fights in the game at that point.
You really only need 4 corner groups, if you recognize where the mobs are going to path after spawning. When they come out, they either go for razorgore, or the controller platform. So corner groups float, keeping between razorgore and the spawn points. Instant cast spells are the key to keep runners from getting away.
Razorgore DPS strat is infintely easier than kiting, and much more fun. I know several people who had come from guilds who kited since day one and really enjoyed the fight for the first time after using a kill strat.
We dps all non-dragons in their corners and have a few hunters and our MT kite dragons. It's still messy but I feel there is a lot more control than kiting everything considering if one kiter dies, it often turns into a mess really quickly. You need to have an even distribution of solid DPS in each corner and alert rogues/tanks picking everything up or stunning. Make sure your Priests know to Fade when they see a Dragon coming for them, and if they can't shake it kite it up the stairs and jump off. Hopefully that buys enough time for a kiter to pick it up. I've seen our druids go travel form and run them around too. Shamans could try an EB totem and boogie I'd imagine.
Does Razorgore ever become a "clean" fight? We have about 2 Nef kills under our belt but had been doing Razor more than that while just learning the instance.
We DPS all legionnaires/mages as soon as they spawn. The 12 dragonkin are handled by crowd control/kiting.
At each corner, the first one out is slept by a druid. The second is chain feared by a warlock. The third is kited by a hunter. We've found that assigning one person to do only the control of one dragonkin is most fault-tolerant. Generally, if we have an extra hunter, that hunter does DPS (in a corner that may be getting behind due to the odd leak) until someone screws up or dies; then, the hunter picks up any loose dragonkin(s). If the players have extra bandwidth above and beyond keeping their dragonkin under control--great. If not--it's sufficient to just remove them from the fight. I generally tell new members who are responsible for CC: "Your one and only job is to keep your assigned dragonkin out of the fight. Anything else you can do is gravy."
The question came up: is there a "clean" Razorgore? Yes, I think that with the DPS method, we keep it as clean as possible. Not having a ton of humanoids in the room really prevents the "control loss" which ultimately is why groups wipe on Razorgore. We tried the kite method several times when we were learning and never really got the hang of it. Plus, it's viscerally more satisfying--we just like to blow things up.
