I just tested Izzerri unholy macro and switched my skills around. I stay at 3.2K DPS for 8 mins.
It is indeed strange…
What DPS do you normally get AVG on single target?
Mine you the AOE(raid) one you have within the set bursts me up to 13K.
However, the single no-CD(raid){expected}… below 2K the single with CDs… same 2K.
Your mma-M+ has me AVG 3.2K for 8 mins
