We still have Nefarian to kill on normal, but we figured out we'd give HC Halfus a couple of tries before clearing BoT and TotFW today since people have talked about HC Halfus being potentially easier or at most not much harder (and definately easier on tactics). Now, we didn't have many tries so I'm fairly sure that more trying could mean success even without asking, but hey, what does it hurt to ask?
Our comp is:
DK tank, Warrior tank
Assassination rogue, 2x Destro warlock, Elemental shaman, Shadow priest
2x Holy paladin, 1x Resto druid
Priest can play disc (he doesn't have atonement in spec but would probably spec into it)
Druid can play balance (and does have full epic feral tank gear from all the crap we've got, but we'd rather not swap him to feral offspec since we can't down Cho'gall without him being a moonkin or getting a new player)
Warrior has geared fury offspec
Theoretically any class can play any spec available to them but the goal is to not have to swap classes since as far as I know HC Halfus shouldn't need class stacking anymore.
Our tactic is:
Storm, Nether and Whelps released. DK takes whelps and storm while Warrior takes Halfus and Nether. We dps Storm down with BL (though we had him at 5% tops before a tank died so we didn't really get that far even though getting him down would've probably made all the difference in the world). At 10ish stacks (60% reduction) a paladin BoP's the halfus tank, he /cancelauras it with a macro and continues until 50-60%ish reduction when the DK taunts Halfus and Warrior taunts Storm rider. DK does the same BoP trick with the other paladin and hopefully after that point we're well into killing Nether and the dps tanks are taking is manageable enough.
Currently our DK has been dropping quite quick when it's his turn to tank, might be his self heals getting reduced by the MS debuff but I don't know enough about DK tanking. There's a couple of seconds of communication before Storm rider actually leaves him, but it shouldn't be it either as he tends to die after that.
We're all geared, mostly full or almost full 359 epic, so it should not be a huge problem.
I'm not expecting a very specific answer since I'm not giving very specific details, but in general is our raid comp or our tactic wrong in any way?
EDIT: To ask in the same thread, with that comp how doable is Nefarian P1? I'm thinking of giving moonkin kiting along with earthbind and shadowfuries a try, but am open to better ideas. Especially those that don't require swapping specs.
