I got it last night!!!
I love playing my 85 much more than leveling. You have to do 85 dungeons now to get better gear. Once you reach a certain average item level, then you qualify for Heroic dungeons where you get even better gear. Then once you have that down, you can raid.
You can also by 359 ilvl gear from vendors from hyjal or TheRazane once you get exalted with them. It's easy to do that though, all you do is wear their tabard while you are in 85 dungeons.
