Cata Impressions

So I am really enjoying cataclysm so far! The new zones are all really fresh- the phasing is a little awkward when group questing, but it does give the zones a more narrative feel than in past expansions. Love love love the Harrison Jones questchain in Uldum.
The dungeons themselves... so far I've been a little on the fence about them. When I do them with guild groups, they go great, but I've gotten into some sketchy PUGs with entitled tanks who seem to think that mana is some sort of healer myth. Actually in general I'm finding healing to be a little crazy right now.

Class selection at 85

So I was kind of on the fence about which of my toons I was going to level first. I ended up leveling the priest first because I was having a lot of fun playing holy at 80 and thought it would be pretty fun to level shadow too.
The unexpected thing for me at least, is that the leveling grind from 80 to 85 was really quick! On top of that, I have an incentive to level my alts, because the questing will contribute to guild xp. So, I think my plan now is to continue leveling my alts and then decide on my main. So here are my general thoughts on the classes so far.

Priest

I leveled shadow for the last two levels, but I did a fair bit of questing in my holy spec, mostly if I was waiting in the dungeon queue and didn't want to bother switching out. Most mobs were pretty squishy, and any spec where I was glyphed for Spirit Tap was pretty easy to level with. I ended up ditching my disc spec after the first dungeon- I had some bad luck with Atonement- I don't think it's practical for a 5-man. It might be good in a raiding environment, but overall I found the holy spec to be really fun and versatile.
At 85 though, I've only run 2 heroics, and I've had severe mana problems. I have to drink after every pull and I and up oom on several bossfights, even when I feel like I'm being pretty conservative with my spell selection. I'm not that enamored with the priest after all. I might try a non-smite disc build to see if the mana efficiency is a little better...

Shaman

So originally when I was picking a toon to level, I was comparing priest and shaman, and looking at all the shiny new toys priests were getting, while shaman seemed a little boring. Now at 85, as my priest, I find myself pretty much healing like I would on a shaman. Sure, I have all these other fancy buttons, but if I actually use any of them (looking at you, Holy Word: Sanctuary), I'll go oom in about 30 seconds and just sit there watching my party members die.
So I'm going to start leveling the shaman in parallel. It's pretty easy to level to 85, and it is all contributing to guild xp, so it's gravy.

Paladin

The dark horse in this race is my paladin- I had this tank alt on another server, and cause my guild there folded I decided to transfer him to BT and start leveling him just to get some mining/ore for jewelcrafting. I am actually still leveling prot, and I really like it! I also am going to look at a holy spec for him as well, but tanks are so in demand I doubt I'll get much use out of it.

I have time to choose, cause my guild isn't really going to start raiding for at least another two weeks.
And then you bet you'd better finally decide...

So, anyone have any initial impressions of healing in cataclysm?
