We've got over 30 attempts on this boss so far, and we can't manage to get past Sul with all team alive...
We are using 2 tanks and 3 healers, 1 tank takes Sul and Frost King and the other tank takes the Priestess. We've assigned a disc priest on our warrior tanking Sul, a resto shaman on the druid tanking Priestess and a resto druid raid healing.
As for the dps, our warrior should be focusing mostly on Sul, helping out the most on the other bosses when Kazra is up. We've assigned lock and shammy on the spirits. (ilvl averages on 505, so we aren't exactly undergeared)
I dont think I've noticed a particular spell we keep dieing to, everytime it seems to be something different... personally, I've found it quite difficult to handle the sandtraps, almost always I get rooted... sometimes DBM doesnt warn you straight away, other times I get rooted before I even start taking any dmg. To handle that I've decided to make a big icon with Power Auras to track the stacks of Ensnared, hopefully that will help.
Thats the only thing that I could think of, really cant come up with a solution!
So, what do you guys think we should change, to be able to kill dem trolls?:P Also, if you would like to suggest anything class specific, please do! We all feel we could do much better, so any tips will be appreciated.
