Here's what I'm looking at:-

Focus is on empowering PW:S and the Holy side of Atonement healing coverage, with as many bonuses to Smite/Penance/Purge The Wicked as possible to increase DPS, atonement healing output and shield/atonement uptime. A few points to get mindbender for mana purposes too.
I must say, on paper it looks like there's a good opportunity for builds that lead to something more akin to the MOP style disc (higher DPS and atonement healing output).
