Thanks for the answer dude!.
Yeah, I basically leveled this alt for my guild as we needed a warlock and so my gear is pretty good for the time I've spent raiding. I'll admit though my soul dies a little inside every-time I spend my coin on Tsulong for the caster sword, and I get LOOT!.... Cloth shoulders. 3 Times now!.
I will keep trying for a new weapon but back to the main question, It's basically personal preference then? or is it better to just stick with 4717 due to reapplying empowered dots often and not getting the max benefit of extra dot ticks anyhow?.
