The most recent verson of Rawr I have didn't support seal procs from Judgements, so I'm interested in seeing how things change when full 3.2 support comes out. If it's true, judging to keep the buff up (i.e. every 20 seconds) would regen, with SoW, 1% of max mana per 5 seconds - basically the same as Replenishment - which would give back what the Replenishment and Divine Intellect nerfs took away.
As for itemization, the big changes are the Illumination nerf (30% return instead of 60%) and 25% better Mp5 itemization across the board. I expect that the stat dynamic has changed from something like 1 Mp5 = 1 Int = 2 Crit with Mp5 seriously overitemized to something like 2 Mp5 = 3 Int = 5 Crit with Mp5 slightly overitemized. Or, holding the value of 1 point of Int the same, 1 point of Mp5 would be, say, 33% more valuable and one point of crit 33% less valuable.
Or, TL;DR: Mp5 isn't worth stacking, Crit isn't worth abandoning, a mix of stats is good, and stacking Int is still Best Practice (tm). But the Mp5/Crit playing field is much more level.
Most interesting is that Rawr suggests that Haste for burst is significantly more valuable than in 3.1, enough so that Mp5/haste and Crit/haste throughput gear both outweigh Crit/Mp5 regen gear.
