It is here! With the help of the amazing Arceopteryx (actually, they made the list and I just edited it a tiny bit with my own opinions...) I can proudly anounce that we have a List of Gear for Pre-Raid Priests. I won't keep you waiting much longer, but please read the note at the end of this post for more clarification.

Chest: Merlin's Robe (Craftable) (*)
Wrists: Bejeweled Wizard's Bracers (Craftable) (*)
(!) As you can see, this item requires Emblems of Conquest, not Emblems of Triumph. It will be a pain to convert, but some believe it's worth it.
(*) The patterns drop at the Trial of the Crusader Heroic 10. It might be a bit rough to find them, or a tailor that can make them. On a positive note: you'll be able to collect a lot of Crusader Orbs while you're looking for it~ The mats for these two can also be a little tricky or expensive to assemble. But they're definitely worth it. (The only argument against that I've heard of is that it needs replacing after a while, but then all gear does, certainly at this gear level. It's called "upgrading". /end snarky comments)
Also: Arceopteryx' list had these for wrists, which are a very nice alternative if you decide not to go for the craftable.
Note: One of the reasons why there are no fixed gear lists for priests is that it is a very versatile class. Everyone has a different play-style and so a different opinion. However, that makes it very difficult for new players to learn the class, and if your brain shuts down when math lurks around, like mine, it can be a little harsh to bite through all of the theory crafting. That is why I made this list. As such, it is by no means an exclusive 'look-at-me-I-have-the-best-gear' list. It is more of a guideline. Any remarks or comments are welcome, especially if you feel you found an item that is better than what is posted here.
I will make short posts on gems and enchants in the near future.
