So tonight since there was no combat log i figured id be all hardcore and fraps the same fight first boss in Eternity Vault hard mode.
My Sharpshooter attempts i turned out to do 394,782 DMG Within a 9 Minutes fight (Im going to keep it at 9 Minutes Becuase thats easy'r math)
Dirty Fighting i Turned out to do 321,871 DMG now keep in mind it was my first time playing the spec and i was Greatly confused on how to play the spec at first.
So the Numbers are
Sharpshooter - 394,782/540 = 731.077777778 DPS
Dirty Fighting - 321,871/540 = 596.057407.... DPS
Fact of the matter is I might be a better skilled sharpshooter, And i also might have speced the Dirty fighting tree wrong as well. If anyone would like to publish their findings that would be good.
On a Boss that has 1,600,000 Health Ive clearly done my share =D
(8 Man Raid BTW)
