Nice summary Klog.
To beat the enrage on a 5m beserk timer you need 6 dps to be able to pull approx 11.9k dps for the duration.
That is a high requirement, as i did not factor in any damage the tanks and healers do. if your 2 tanks can manage 10k dps between them (approx what Klog and I managed) you need the rest of your dps to pull approx 10.2k a head. This is single Target dps, there are no adds in this fight.
If you cannot sustain that you will not beat the enrage.
Fun Fight, will be loot pinyata once more people are geared.
"Uru, your dps was pretty Imba
