i understand why it is usefull for mut but fact is you could just aswell replace rupture with a buff which is passive or tied to SnD because rupture is realy weak for assassination also there were times where the debuff from Hemo applied this i think it was 16% debuff on the boss it got removed with MoP tho
also how is talking about how unviable sub is in ToT related to anything in this thread well all know why sub sucks in MoP we dont have to point out its problems
