I've read bits and pieces of it and a few things made me warm and fuzzy inside.
Blind becomes a physical attack, so you can't dispel it anymore and it costs no more reagents
Retribution paladins become viable dps (I'm sticking to protection because everybody can do dps these days)
Engineers can make their own flying mount!!! The roflcopters will soars through the skies
(ps big flying birds are for the weak, real men/woman build their own flying coffin
)
Shaman getting a buff as well
mages get 10 pve buffs or so
All in all I'm very excited
going retri for a bit, getting engineering maxxed out is my top priority for now
Anyway check the wow forums for the info!
