Uldar Gear Selections
This is the spread sheet I've come up with to help figure out some questions I had about what my end-game setup would look like after Ulduar. I apologize for the VERY poor setup, so I'll explain it very quickly. The top set of gear was my first crack at what my Ulduar gear would look like, and the 2nd set below it is my current gear. The comparison after my current gear is the difference in stats from my current gear to that first Uldar gear set. The third set was my 2nd crack at an Ulduar gear set where I switched to the crafted cloth belt and switched from the Frozen Loop to the Pyrelight Circle (Signet of Manifested Pain has slightly more int but all the other damage stats are the same so I chose it over Pyrelight).
The comparion at the very bottom of the spread sheet is a comparison between the 2 Ulduar gear sets. While both sets are extremely close, I'm leaning towards the cloth belt/Pyrelight combo over the mail belt/Frozen Loop combo. A 22 spellpower gain (gemming the way I did) while losing 13 haste 3 crit and 3 hit definitely feels worth it.
The only real change I'm considering here is not putting Reckless Monarch Topazes in the neck/back and just putting Runed Scarlet Rubies there instead. As Ezareth pointed out earlier, I'm worried about Lava Burst wait times. Although I'm not sure the wait time on a Lava Burst would outweigh the gain on a further hasted Lightning Bolt.
Another thing I was thinking of, how will the T8 2 piece bonus affect crit scaling while we have that bonus equipped? I imagine the dps value of haste and crit will be a bit closer when taking that bonus into consideration.
