This is completely up to discussion, as I've only been fiddling with this for a day now. I posted the over at EJ, but I thought I'd post it here as well to get your guys' input.

Basically there's a few gear choices that are a little different to what you'd think - like hat being off-piece and not resto, and using a couple of int/haste gems in red sockets. This profile reaches 8089 haste (right on the breakpoint) and 5105 hit (5 over cap), so in terms of wasted stats, this setup has virtually none. The only possible way you could improve the DPS beyond this would be to either: a) remove some mastery pieces or, b) turn some 502 -> 509 but run the risk of wasted stats or more mastery. I don't think it's possible to do either of these (or a combination) and still go higher than 108023.37 DPS.

note: all numbers and gear have been evaluated through WrathCalcs. Using SimCraft/Rawr or any other evaluating tool will most likely give you different numbers, so for comparisons sake, just use WrathCalcs when wanting to make a suggestion.
Also, you have to be signed into Wowhead to see the profile, it's a bit odd but oh well.
If you can personally find a better DPS output through WrathCalcs with a different set-up, post and I'll check it out. For this build, best DPS talents are Incarnation and Dream of Cenarius by quite large margins.
