So after wiping on Kalecgos for 4 hours a night since Sunwell has been up, it's needless to say we've tried nearly everything and we are at the point where we feel like it's pretty much useless by now. Most of our players are nearly full T6 and we've been farming Illidan for months now, but for some reason we're dying repeatedly. We've gotten him to single digits numerous times, but never a kill. Our GM is adamant about us wearing some shadow and arcane resist (Medallion of Karabor, Violet Eye Trinket/AR Cloak) and I don't know if it's helping at all. Also, sometimes portals should spawn but they dont, seemingly skipping over a group.
I need any advice in the worst of ways, because at this point i'm ready to just throw in the towel and wait until wrath. It just bothers me that we could literally walk through BT/Hyjal in a couple weeks, now it's taking us a couple weeks for a boss that appears to be easy. We just don't know what we're doing incorrectly.
The raid makeup is 9 healers, 3 tanks, 3/4 decurses, and we use a 4 portal rotation. Halp!
