Mana regeneration (or mana conservation), new talents like Chakra, the Archangel/Dark Archangel look very interesting and I think all priest would like to know if they modify a lot the playstyle (something Blizzard has announced several times). Also the "I got some spare time to dps since nobody's going to die soon" and the mana regeneration via dps.
If you had a pally, the Holy Power mechanic is my main concern right now for that class.

@Kurnak

Actually, I *do* have a level 80 Paladin, but I'm not very good at playing it. I might try that out though :D

Yay - more people I might happen across on there... now if only they'd sort out the character copy I'd be a happy beta tester. But I've only just begun the process too!

Anyway if you need a tank and you're on in the odd hours look me up :)

@ Miss Medicina

Thanks for telling me :-P

Two things:

- Yes please on the Holy Power!
- Healthpools for lvl 85 tanks. I MUST KNOW! Doesn't large healthpools for tanks help healers ;-)

Prod me on twitter when you get online and such if you'd like an invite to the guild we've got going on Lost Isles (US/PVE/Alliance). We're level 5 at the moment, so extra XP, extra rep, extra mount speed... :)

Kurnak, Fuubaar, I'm happy to answer questions about Holy Power as I'm primarily playing my pally on beta. :)

If you can give the pally a shoot that would be very sweet Jess.
Since it's the class it has changed the most we're going to need some time gettng used to the new playstyle and getting rid of old habits.
Anyway the priest also got a good revampand since it's your main all feedback will be very welcomed, specially on the disc spec.

Tales of a priest did some commentary on holy but we are missing how disc plays out.

Disc healing, how Archangel works out too would be very interesting. Also, I'd like to know from a healing standpoint, how important it may be for dps classes to consider their own survivability talents/tools in group setting, or of healers won't really care much.

Disc talents please, how they feel for both leveling and 5 mans.

Mana regen, although that will be hard to figure out as I doubt you'll be raiding in beta.

How's the new PW:B work? Is it any good?

A clear and simple explaination of how Archangel and chakra work, perhaps with a couple of basic examples of how you think they might be useful.

The most noticable differences when you first start healing in the beta.

Don;t forget to have some fun in there too ;-)

Gobble gobble.

Disc healing, Lifegrip...

And are there still Dalaran mobs in Amberpine and is the chicken-seller still at the racetrack in Shimmering Flats?

Dicipline!

I've hardly been able to find anything about the state of Disc in Cataclysm. Specifically, healing in groups.
