I play a warlock specced deep Destruction. Mainly because I like throwing fire at things.

I've been doing HM ICCs for a while, and see some very nice gear drop, though I'm reluctant to leave my T10 (4 set) bonus. I was just wondering; is there a point where I should drop down to the 2 set and get better gear with better stats, or should I just stick with 4 set?

I only have 1 piece Sanctified, but I'm working to quickly change that.
I spent a lot of time around Elitest Jerks, but the Destro Warlock section has a very limited part on the T10 bonus; it's definitely still a WIP.
