New Holy playstyle???

That's the tree that I'm probably going to use as holy, and I'm thinking that this archangel talent could be pretty boss for holy priests, it gives you 15% mana back, which i think is what you would spend casting the 5 smites on the boss during some downtime. You have 15 seconds to get another smite off. Then boom, pop angel, GS and start spamming some POH and COH and you just healed the whole raid. There still isn't a timer on how long archangel will last, but i would think 15-30 seconds? I think that holy priests are going to be one, if not the top healers again in higher end Cata.

And disc priests having the ability to get silence? I'm not saying that they will, but its a possibility. Boss healer in an arena

IMO:

Healing > smitespamming to get mana back

It's like how with PoH, casting PoH twice in a row is better HPS than PoH -> FH FH FH -> PoH. In the time you spend spamming Smite, you would have already healed what you needed to heal.

I've been looking at the new trees and it looks at first pass as though I saw 4 possibilities:

1) Smite-based Archangel, might look something like http://www.wowtal.com/#k=d0OiQDK_Z9uL00.9dw.priest. Strengths is that it donates some DPS and looks to be really very efficient. Downside is that you end up spending time casting Smite rather than healing. Also since you devote some talents to damage you don't have as much straight healing power or utility.
2) PW: Barrier, might look something like http://www.wowtal.com/#k=9fgcI0k_j925j_.9dw.priest. Gives you a nifty cooldown and lets you get more of the Holy goodies.
3) Archangel + Barrier, what the OP posted. Gives you both the benefits of the above build, but doesn't quite do anything as well. Still requires some nuking to make it function.
4) Inner Focus/everything else in Holy, http://www.wowtal.com/#k=dI0JYzvW5OJKO.9dw.priest. You can get every PvE-oriented talent in Holy and have 11 left over exactly.

Obviously testing, theorycrafting, etc is going to go into figuring out which of these are the best. It'd be nice if all four were viable, but I doubt it'll turn out that beautifully.

If you really want to do a smite hybrid holy spec for PvE this would most likely be a better option. We cant predict what healing is going to be like but I doubt you will have enough chances to start spamming the hell out of smite enough for archangel to be worth it.

Top healers. Sadly I think not.

This is what I believe will be the case:

Chakra – When you cast some spell 3 times the priest enters an empowered state allowing the priest to cast that spell nearly as powerful as all other healing classes. To compensate all Holy Priest spells will continue to do less healing yet perversely cost more mana than other classes when not affected by Chakra.

Progression healers will be more about the healing talents, but when content turns to farm, I foresee smite spam then heal.
