Gear Question

[Azrogol]

So I currently roll as 2h frost; I would go Unholy, because it's more fun, but I'm sitting at 528 Ilvl and 2h frost is just performing better, and on the previous thread I made it seemed like the consensus was that Unholy doesn't start outperforming until you start reaching the higher echelons of gear (i'd be dw but getting 2 weapons to drop is crap). That being said, I do ~120k to ~160k dps right now; around what ilvl will I be able to push 200k? Are there any trinkets/specific items I should be saving rolls for that will significantly boost my dps?

From a quick look at your armory

Replacing the ticket by

Thok's Tail Tip (Any level) and Evil Eye of Galakras (Any level)

would be a massive dps boost for you.

and a weapon from SoO

like
Greatsword of Pride's Fall
