Might want to replace Tarnished Raging Berserker's Helm - Item - World of Warcraft with Stained Shadowcraft Cap - Item - World of Warcraft because crit outweighs haste.
Same goes for Inherited Cape of the Black Baron - Item - World of Warcraft You'd be better off with Tumultuous Cloak - Item - World of Warcraft
If you're capped on hit (which you are) you'd be better off with the Upgraded Dwarven Hand Cannon - Item - World of Warcraft especially since you're a dwarf
For a belt i'd choose bandit over wild, 2 more stam and crit instead of haste.
Signet of Argas - Item - World of Warcraft >>> Protector's Band - Item - World of Warcraft More agi, more stam.
Might be better off going horde for a second signet, unless you're keeping DPR for the critbuild.
Tarnished Leggings of Destruction - Item - World of Warcraft vs. smelting pants is debatable 6 stam / 4 haste / armor vs 2 agi
Ofc Arena Grand Master - Item - World of Warcraft wouldn't hurt.
The weapon I want to keep my bow![]()
You could always use the gun and transmog it to look like the bow?
I don't have the gun >_>
And I don't have a level 90 anymore.. so it'd take a while :\
Is that a Death Knight?
