I have the Justicebringer and Citadel Enforcer's Claymore as my other wep. I'm wondering which will show a dps increase as unholy with my current gear, or what will scale better as i begin to get my t10. Also what gem i should put into Justicebringer, as i have yet to gem it.
And to add to what was said earlier. Dump the leather and agility/AP gear. I know you're like "oooooh, these boots have a lot of crit and ap and ArP on them!" but it's just not really worth it. Strength is just too good for a DK to pass up.
Also replace any yellow gems with str/crit gems (provided the socket bonus is 4+ str) and only fill in one blue gem with a nightmare tear, and replace your cloak enchant with the haste one.
Cloak: change gem to str+crit, change enchant to haste
Chest: don't be cheap on gems
Wrist: get an enchant
Gloves: change the gem and get rid of the hit, also get an enchant (15str or 44ap)
Belt: get a belt buckle
Legs: get rid of the hit gem, also get an enchant on it
Feet: get an enchant on it (32ap as you won't need icewalker)
Trinkets: try to replace your lower trinket, you're having way too damn much hit rating, which is a waste of dps
I know you're asking about weapons here, but there's so much wrong with your current gear, you can get much more dps by just sorting that.
