My guild is currently progressing on H Megaera 10 and we are having difficulties getting to the last few rampages. I am not sure which area needs to be improved (DPS? Mechanics? CD management? Raid Positioning?). We are using a strategy with one tank on the heads and the other on the adds for interrupting and stuns. Someone seems to die generally to ice beams and there is occasionally some bad ice placement. We have healers stand just in range to heal the tanks and ranged DPS stands at max range.
Our rampage CD rotation looks something like:
1 - Guidance, Barrier*
2 - Tranq, Rallying Cry, Banner
3 - Devo - Devo, Treeform
4 - Guidance, Hero, Barrier
5 - Tranq, Rallying Cry, Banner
6 - Devo - Devo, Treeform, Guidance
*Spirit Shell is used each rampage.
I play the Disc priest so feel free to add any productive criticism. I've linked the log of our best try.
