That's pretty cool, I didn't see the full table either so thanks!
I didn't mean to to make it sound like I was bragging, it's just that I wouldn't have gone for this setup for if we had all of our core raiders :P Bubblemaker was Ele, and therefore was able to drop his Magma totem and Fire Nova the adds, while still maintaining single target dps on Halion, which will explain why he topped :)
In terms of healers, I love my Holy Priest and Holy Paladin the best out of all of my characters, and I do admit having a great Holy Paladin in any raid is a must.
Even with 4 dps in Shadow, we were able to balance out the Corporeality, as they were pretty much BiS melees, with a 100% uptime on the boss, unlike in Physical Realm where there is constant switching of targets.
As for tips, just make sure you have a raid composition that includes classes able to AoE efficiently, to get the adds under control. Also make sure your leaders on RaidCall (or TS, Vent etc) are able to stay calm, and give clear instructions. Your raid members also need to be able to listen to your commands, so when you tell them to stop tunnelling the boss and kill the adds, all 19 dps (or whatever you're running with) do it!
Good Luck but more importantly, have fun with the fight!
