The trick to this fight is 2 healing it, just call out targets and nuke them down fast. while 2 players interupt the 2nd and 3rd adds that come up. Rest of the dps all focus the same one untill its dead, then move on to the next called out target
Damage on your raid isnt that high, if the right mobs get interupted so really no need for a 3rd healer
On 3rd phase all move stacked up away from ice orbs and aoe, on4th phase get melee out of range from the guys on the bears.
Pop hero on Jalakdude and it's a sure kill
(btw our raid ilvl is about 495 ish)
