I'm seeing a ton of nice changes. Looks like a pretty big patch.

Mounts @ 20 and 40, flyers @ 60: I'm kinda "meh" about this one, but I'm an old timer that had to walk barefoot (on my trolls, that is) through snow (in Winterfall), and uphill for my questing.
Shaman totem bar: Freakin' bad ass! 'Bout time, I'm gonna have to call that a major shammy buff.
Emblems change: Also pretty bad ass, since I don't raid either.

I also like the changes to stuff like WSG (not that I've been in any BG since level 70, but still if I ever want to farm honor again, it's a nice change)

PvP experience (with the ability to turn it off): May instill enough interest for me to make a 5 man twink PvP team.

Over all, can't wait for the patch. I'm actually not playing right now since I have a lot of 'summer' stuff going on, but will probably reinstate my accounts soon.
