So my 2nd spec is Holy. I've attempted to shock for dps, but I wouldn't count on myself for it. This is pretty much cookie-cutter here.

I didn't take Imp Blessing of Wisdom (tier 4) so I could have Imp Concentration Aura (tier 4). It's a bit more situational however. ImpBoW might be better overall for the raid. The rest of the talents I didn't use were more survivability for PvP, or utility that I didn't have enough points for. Things like Purifying Power (tier 6) weren't worth it to me, since Benediction (tier 1) over in ret covers that. Even a dispelling machine like me won't notice much of a mana usage difference.
Divinity (tier 1) is a nice addition, though I've had to find points to take out of Ret from Sanctity of Battle (tier 4) and Pursuit of Justice (tier 3) to get it. Previously when Blessing of Kings was in its place, I didn't even take it.
On the Ret side, the tier 2 talents are pretty open. You can go for utility with Imp Blessing of Might and Heart of the Crusader, or Improved Judgements if you want to shock. These talents are necessary to get Conviction (tier 3) and beyond.
