boxed

I'm curious as to whether or not I follow simcraft off of a cliff. It's telling me my weights are Int: 1 Crit: .61 Haste: .54 Mastery: .52 It is telling me that Mastery will eventually be more valuble than everything else because of the way it scales http://cl.ly/image/053z0G3k3l1U but other similarly geared locks are getting wildly different results than me. Can somebody confirm this is correct? It would be greatly appreciated. http://us.battle.net/wow/en/character/kiljaeden/Warlolck/advanced
