Well, looks way better then I expected. Over 8 DS per minute if I'm right, which is a good start.
BT-uptime is a bit low, I'm a fan of macroing it into my DeathStrike, but that's VERY debatable.
Like Nillo said, his DRW-uptime could be up to 50%, which will improve his DPS.
Armory looks good, some reforges are a bit off, he reforged off mastery on his trinket, or his weapon from crit to hit, some gems can be changed.
We figured that out, you posted a kill ;-)
The CD on DRW should be 45 sec, while the duration is 24 seconds. (On ultraxion. Normally 90s CD and 12s duration)
