Hello Sherkan,
Ill post my gear later, for now here is the skill build, stat build and devotion build for the 17k DPS toon
http://grimcalc.com/build/mwk3Wa
Gear is just a bunch of easily found epics, rares and yellows, prioritizing these rolls
+Primal Strike
+All Skills or Shaman Skills
+Lightning% Damage
+Flat Lightning Damages
+Attack Speed
+All% Damage
+Physical% Damage
In my opinion, +Primal Strike is the best roll to get on gear as this will boost your DPS tremendously. I think I have a +Primal Strike on Helm, Belt and Medal and +Shaman Skills Amulet.
Also my rifle has a i think 27% Attack Speed with Lightning% Damage.
