Re: [10/25] Thorim's Arena
So we finally killed this boss, in case anyone else is having issues here is what we do:
3 tanks - 1 Warrior, 1 Pally (me), 1 Feral Druid with 600 resi
6 Healers - 1 Holy Pally, 1 Resto Shaman, 1 Resto Druid, 1 Disc Priest, 2 Holy Priests (my guild just has lots of priests)
7 Melee - 4 Rogues, 1 Dk, 1 War, 1 Ret Pally
Rest ranged
All ranged go tunnel with the prot warrior, and 2 healers. In arena I tank warbringers and keep aoe down, the druid tanked champions. We had 3 of our rogues spec throwing specialization and basically spam fan of knives for the entire phase. That keeps the evoker locked down, we have a 4 person disarm rotation on the champion. Once each one is brough into the middle someone disarms them and then they are burned down. Champions and Evokers just die to the random AOE. Our kill priority is Champ->Warbringer->Evoker. In arena the shaman isn't really healing much, his primary job is to keep the evoker shocked and purged at all times. If that shield stays up it could cause an annoyance. With that set up our arena can basically go on forever. The healers tend to stand outside the circle to avoid the slow, and if adds come to them they run through the circle and reposition on the other side.
Ideally tunnel gets to the top with time to spare, we like to activate the boss right after a champion dies but before we get another one. When thorim comes in I taunt, pop wings, and get tricks of the trade and MD. My job is to put out as much threat as humanly possible before first unbalancing, on first unbalancing the prot warrior taunts and builds more threats. This whole time our feral just basically gets his bleeds up and gets his rage up. On third unbalancing druid taunts, he tanks until he is dead. At about 6-7 charges you have to start having cd's for every unbalancing, as they will be hitting for 30k+ without them. At about 11 stacks, we had the holy pally beacon the prot warrior so that there was overlap. Once the druid dies, the warrior shield walls, and taunts, he uses all his own cooldowns plus any cooldowns we have left and tanks until he dies. When he dies I taunt and use my CDs. If the boss still isnt dead you can have a stone on the druid, but if the boss isnt dead your probably not going to kill it.
On our kill attempt our druid died at 15%, the warrior died at 2% and I get to feel next to useless. While I am not tanking, I kept sacred shield on the druid, and cleansed healers when I had the mana to.
As for the rest of the raid, you want them spread out around in a circle in groups of 3 or so, we did 5 such groups. If they get a lightning charge in there area, they run behind the group to there left or right, but make sure they are far enough away to avoid chaining lightning. It will take some practice for all your ranged to figure out the sweet spots where you are close enough to avoid blizzard but far enough to not chain onto melee. When you figure that out the whole phase gets smoother. On your first kill dont expect 25 people standing, when the stacks get high, people are just going to die from damage, your goal is to make sure everyone is alive until 12 stacks or so, you have to have very good dps to get him down.
Thanks everyone for all the tips and suggestions. Hes finally dead, next week Iron Council.
