We tried killing Sul first on our next raid night, got it on our first try.
Council of Elders seems quite hard on 10N. We're well on our way to getting it (~30% or something last night) but I'm curious about others' experience with the fight.
Currently we're 2 tanking with the tanks swapping ice lord, and 3 healing. We're having trouble dpsing the bosses in time (before full energy), but when we 2 healed we had deaths instead to the frost debuff, sandstorm etc. We basically have no strategy for positioning and are spreading loosely about the middle of the room.
When I heal, I feel like the damage is very high, and very spiky, where I would expect 3 healing to trivialize the healing requirement on a normal mode encounter.
25m discussion welcome, though I expect its totally different :P
