Except 24 seconds of 15% increase DPS is only a 1% increase in overall DPS of a 2:30 fight...which is what 60 DPS? As to RNG i probably did crit a little more then I should but full raid buffed im close to 60% crit anyways.
@ person who said 2 more minutes would lower my DPS...no it would increase it because i would have berserk up again (3 min CD)
