My guild is currently working on normal Rag 10 man. We're having difficulties even getting close to killing him (50% has been our best attempt). I know we're having problems with people avoiding fire waves and killing their assigned add during the transition, but even if we don't take any damage from the wave and no adds hit the hammer we still have troubles.
Our raid setup:
Tanks:
Prot Paladin
Prot Warrior
Healers:
Two Resto Druids
Holy Pally
Holy / Disc Priest (Generally holy)
DPS:
Two Rogues, one Combat one Assassination
Arcane Mage
Balance Druid
Affliction Warlock
Ret Paladin
Elemental Shaman
We occasionally have a Destruction Warlock and a Marksman Hunter, but neither are reliable with work and college schedules
We've switched around healing and the dps that come. Our assassination rogue and arcane mage have been in for every attempt, along with (I think) our ret paladin. They'll likely be in for most if not all of the progression on rag. The other two or three dps rotates depending on the night.
Generally we start the fight with tanks on the right side and melee on the left, with the rest of the group spread loosely throughout the platform. Tanks are switching when our stacks drop off, which is usually between 2 and 4 stacks on the other tank. Our mage is detonating traps when one of our healers call it out, generally right after it spawns. We try to use aura mastery and divine guardian on as many of the trap detonations as possible.
When we get to 70% and the transition happens, all of our dps and our two tanks are assigned to a specific add. Last night we ran with two healers so we had someone on every add, previous nights we used three healers so our holy paladin would be assigned to stun an add giving dps time to kill their add and switch to his. We frequently have problems with people not killing their add. The tanks' adds always die due to our long stuns, but our dps have issues killing theirs. Specifically our druid and arcane mage if the hammer falls next to their add. Our mage has started saving PoM for his add and didn't have an issue with it afterwards.
After the adds die we once again spread loosely, but this time on the left side. Whichever tank had the boss before the transition picks him up again. When the fire seeds spawn we immediately switch sides and we stack in melee range on the tanks. If the platform in melee starts burning, we move slightly back so we're just outside of it. After aoe'ing the adds down we spread loosely on the right side and repeat, this time running left. We haven't made it out of this phase.
Is there anything that we're doing wrong? Anything we could change to make the fight easier for us? We seem to be losing people when the seeds spawn or when they detonate. We use aura mastery and divine guardian again as the seeds detonate, but we can only get the first two. Our mage has suggested that everyone stack before the seeds spawn to allow us to aoe easier, but that seems as if it would increase the damage we take significantly.

Thats our WoL report for some of our attempts last night. I didn't record all of them because I didn't think to until after raid started and I thought we were calling it so turned off logging and forgot to turn it back on for a couple attempts when we decided to keep trying. Last night was our first time trying to two heal, because two of our healers couldn't make it and we didn't want to waste the raid night. Last night was also our best attempt but our resto druid doesn't want to continue two healing although our holy paladin does.
