Nice Rogue 9/10 I would change Eyepatch to loomhead, so you should gain 5crit for 3hit and 1stam. If you lack the 3 points hit rating, you can change one Argas to RoP.
Tradeoff would be 4 Stam for 5 Crit if I remember correctly.
I don't rate anymore but you need leg armor, shadowfang in off hand.go back to double argas. Defias belt , band of Serra wrist, since u went for darkmoon shoulders if u were in crit build then u would have boa shoulders on. Also this rogue looks like an old lvl 19 rogue please don't tell me it is it takes literally few hours to gear a lvl 20 rogue. BesidesLvl 21 rogue > lvl 20 rogue in current patch
use Doomspike MH, SF off hand, (unless you go assa then use 2x doomspike)
Defias belt scales to 8 agi 5 stam (you can use stachel belt 6 agi 6 stam 6 crit, personal preference)
