I'm currently using the 346 Robes of forgetfulness and I'm wondering if the crafted Chestguard of Nature's Fury would be an improvement if I reforge some of the crit to spirit?

It is a big intellect boost but I lose gem slots and haste. I'm planning on running 10m content and with the 4.0.6 patch I think the mastery will become a much stronger stat for druids with the ability to roll Wild Growth almost non stop and rejuv much more often. Also if you notice any other big upgrades that I could get easily (like crafted epics) please let me know. I've got jewel crafting and Alchemy so I'll be equipping my epic alch trinket as soon as the patch hits.
