Alright - so let me preface this by saying a bit about my guild. 5/7 HM 10-man, easily burn through 4 HMs (Rhyolith, Shannox, Alysrazor, Baleroc) in about an hour and a half without any problems.
But we just mash our head into a wall on Beth'tilac. It's just not even funny right now. We need some help.
Raid Comp:
Protection Paladin
Protection Paladin
Holy Paladin
Restoration Shaman
Holy Priest
Marksmanship Hunter
Affliction Warlock
Arcane Mage
Feral Druid
Frost Death Knight
I have a few other people I can bring in off our bench (another Arcane Mage, another Marksman Hunter).
So here's my thoughts right now - we want our Holy Priest to go disc (it'd be helpful) but he hasn't gotten it down yet, and he's more comfortable holy. We've tried having our hunter solo the spiderlings and soaking the broodlings but it seems to be too much to him (yes I've seen the videos of hunters doing it but apparently ours can't, and he can barely manage the adds solo without some help). We originally tried Hunter/Priest outside handling the adds (priest helping with broodlings and keeping them both alive) but that failed miserably since it was basically draining our Shaman's mana.
Sunday (we raid Tuesday, Sunday, Monday) we're going to have him over there with a bit of help from our DK tossing out anything at range (we don't want him to get screwed by a fixate) and backstopping the broodlings our hunter misses and our Holy Paladin trying to hit a few broodlings and keeping the hunter/DK up.
We tried using our Holy Paladin upstairs but found him to be more useful downstairs healing - so now we're sending our holy priest upstairs (we're still hoping he learns disc and is more useful downstairs). Our feral druid is going upstairs as DPS on the first two upstairs, but the third one he's staying downstairs (that's the plan at least, we never get that far - in fact we were having so much difficulty we started keeping him down).
We keep our lock and Mage on the spinners and DK helps on spinners (especially taunts) and spiderlings when needed (though while spinners are up he's not very helpful on spiderlings). During first smoldering devastation we're popping DG, second we're doing Aura, third we're doing a DG until Beth comes down (but we're not getting there).
Is our hunter just failing? Should I just dedicate two-three people to the spiderlings/broodlings even though fixate can screw us? Should I just replace our hunter until we find one that can solo the adds? We've got markers on the caves.
What other advice do you guys have? Anyone have any better ways of positioning our raid/strategizing this fight?
I know it's tough without seeing our players and knowing their strengths and weaknesses but any help you can offer will be helpful.
