Garçon! A pair of new underwear please.

Sadly it looks like the some classes have little/no changes. Here's a breakdown:
Death Knight - little/no
Warlock -little/no
Warrior - Deep wounds is unlinked from Impale
Hunter - little/no
Mage - little/no
Paladins - some minor changes, mostly to wording, and spell effects.
Priest - High-tier changes: Chakra, Shadow Apparition, emp Renew moved, PW:B,
Druid - LOTS, including 3 new balance abilities, Tree form CD with 30% movement tax, little/nothing for Ferals
Rogue - Few changes, but lots of things moved around, especially in early trees.
Shaman - Lots of shiny's for enhancement, a few for Elemental (yay earthquake), few for Resto

These are kinda lacking. There are still +hit talents, boring +damage/+healing talents, and some things we know are going the way of the dodo: Toughness for enhancement, aspect of the viper, mana & melee references on a hunter, Master Shapeshifter referencing tree form, no mention of Nature's Grace having charges.

I do find it interesting that both resto druid and resto shaman have abilities that effect them doing damage...

Regarding the resto specs doing damage..

Is it possible that they are giving resto druids the ability to kill things? Now that we aren't confined to tree form 24/7 we may actually find some use in our damage spells!

About time.

I really want to assume you're referring solely to those changes currently visibly in place in the alpha files.

Because if you are saying that based on the cumulative evidence to date, the hunter class appears to be getting little to no changes, politeness will dictate that I ask you how you enjoyed your year on the space station.

These are nowhere near complete, of course. All we have here is a taste, just a small taste, of what's to come.

Damage talents for healing specs are probably there to make leveling as Resto less frustrating, and may also give healers a bit more utility in PVP (important if heals are less vital than they are now) or in content they vastly overgear (my Holy Pally wants to do more than 500 DPS in H-VH, thank you very much).

The changes to Balance are drool-worthy. This hardcore Feral may even consider chickenform in the expansion ...

Eh, nah.

Garçon means boy.

How about a couple less crabs or kobolds and give us some new player models? Seriously, if I have to lose out on seeing a few less better-than-me-looking kobolds in order to get some skin for the guy I'm investing all my time into so be it.

@Grovinofdarkhour

Yes, I was. By saying there were little to no changes, I meant that there are, at this moment, no changes of the Class Talent Trees between live and leaked cataclysm alpha realm from link posted in post. I focused first on the Warlock/DK/Druid/Shaman trees, because those are my 80s. The Alpha trees posted for DKs for example, has absolutely nothing concerning the changes we've been told will be happening.

To be clear, I wrote that Hunter trees are not complete. There are still references to mana cost and ammo in the hunter trees, which we know neither will exist in cataclysm.

Reading comprehension with context is key. Even when you play wow in space.
