Pretty much ! Obviously the longer you stay in void form and push that void form length , your DPS will increase . From both the increase of Mass Hysteria %, the haste stacks , and then finally the lingering insanity when you ultimately come out of Void Form . Remember you should , if possible get back into Void Form ASAP . You get a flat 30 % increase on damage to all spells , so even if you had 40 lingering insanity , going into void form you ' ll pull more . In regards to my actual average , it is dependent on the fight . High movement , it ' s going to be a lot lower . Multi target , a lot higher . As long as PreS 2 m you ' re around 210 k you ' re doing pretty ok . STM is a ridiculous amount of % of total damage you deal , so pres 2 m focus isn ' t AS important . I ' d state work on your Void Form prolonging . PI as late as possible , Void torrent at low stacks to keep your drain rate from going up while gaining stacks etc .
