Today we started progress on Magaera, we put in a solid 5 attempts but we seemed to get a bit overrun on the 6th head, and by the time the head's at around 30-40% we wipe.
We're doing G>R>G>R>G>R>G method
Overall, our raid DPS seemed low tonight. I believe mine was also low, [Evil-Hellfire], what am I doing wrong?. Below is the link to our most stable attempt, i.e no random deaths/panicking etc. Unfortunately I can't post links so this will have to do.
Two reasons why you might die.
a) Tooooo many green heads. Poison bombs everywhere. Too much damage. From the ice beam you litereally take 0 damage if you do it right.
b) Your Warlock and Monk are kind of low. They should be able to put out more.
For you - I'd recommend BM for Single target fights. I can pull off way more than with SV (maybe I'm doing something wrong as SV; but still.)
