That's what I'm saying. Your tree looks amazing and the priest tree, by comparison, looks bland. And I'm not saying that to try and bring the paladin tree down - you guys deserve fun toys. But the priest tree is just...I don't even know how to bring it to words.
That's a little ironic. Before these changes went, Paladins looked at the Priest trees and were colored with envy a bit.
Path of the Devout is there I imagine for those moments in PVP/PVE where you *know* you can get away, but you just want some extra boost to safely protect yourself. That whole tier is dedicated to movement speed.
Divine Star, Vow of Unity and Void Shift are still fun spells. People grief with Leap of Faith, and that's just something that kind of happens - it's like asking Blizzard to chose between fun design or catering to derps who want to troll their raid.
Furthermore, Paladins have been asking for Sacred Shield for quite some time now. Call it nostalgia, or call it a really well designed spell - but it was very popular when it was around.
Our Level 75 Abilities are all tied to Avenging Wrath, so while it may seem like it's very fun (and I'm sure it is), try to remember that it's not all the time.
Finally, the last tier is something that I think is creative and really doesn't fit enough with the Priest toolkit to look over the aisle and say "I'm jelly, bro. :(" All the spells there have a short radius, have damage and healing properties and work very well with the overall look and feel of the Paladin class.
You have nothing to worry about, friend. Your priest class and mechanics look very clean.

I think it was the great feedback provided by paladins that got them to step up their game with the paladin trees. It's a shame the same wasn't applied to the priest trees.
As someone else pointed out, the tree has a very clear cookie cutter spec that I, and probably several other priests, can see forming. The talent you mentioned is indeed on a tier with movement speed buffs, but there's no way I'd take path of devout over the talent body and soul. 4 seconds is usually all you need to get out of something bad, plus the added benefit of a shield in there as well. As pointed out, levitate drops off if you get damaged by anything at all. Going into a fight knowing you can cast a shield on someone and have them be able to move and be safe from damage compared to casting levitate which removes the jump function, falls off from damage, and only offers a 25% buff compared to a 60% buff is no contest at all. Previously body and soul was relegated to holy priests as well, and now it's essentially being opened up to disc priests as well so its usage will skyrocket.
I hate to say any definitives but that is one of those talents that has no use at all and is absolutely eclipsed by the others in the tree.
"Fun" isn't necessarily conducive to "useful" most times. Lifegrip is a fun spell, but how often do priests remember to use it? The good ones certainly do, mind, but the rest probably have no idea where it is in their spellbook.
Divine star is going to depend on a few things, the most important of which is whether or not it's something the priest will be able to control or if it's going to come with all the awful pathing issues of say, a mage's flame orb. The last thing you want is to pop a healing CD and watch it fly off over into a corner and come back without hitting anybody at all.
With regards to void shift and certain other talents it's going to depend on if the talents in the builds mesh with each other. Will final prayer work with void shift? We'll have to wait and see. But then imagine having 3 priests, holy, disc, and shadow all in your raid group(assuming 25man comp) and all of them have vampiric dominance. That's going to be just a ton of passive healing flying around. I think about that and then I think about vow of unity and the fact that any damage taken to the target will effect me too and one of them seems more appealing than the other.
Lots of these things will require testing, so like I said, it's hard to judge either way until we can get into the beta and put it through its paces.
Additionally, most of the talents on the priest tree are talents we previously had anyway. So like I said about the familiarity - it's all still there. We still get serendipity, we still get instant flash heals, etc. That's not so much new as more of the same. And that's really fine, I guess. But there's nothing OMG revolutionary about it.
From a healing POV the class is obviously still going to be as solid as it is now. It's just not going to be any newer or different save for a few gimmick spells, which I guess is okay. I wouldn't play my priest now if I didn't enjoy it.
I just can't wait to get into the beta to really test things out. It's hard when all you're doing is speculating on something from a calculator on a website.
