New EVERYthing mounts and anything you could ask for comes with Wow Cataclysm the test realm was recently updated and showed a few of the new mounts. Reins of the spectral steed/wolf are some sick looking mounts.
raids are adjusted so that both sizes drop the same quality of loot and chance of loot.
new lvl cap of 85
all in all i give it a 8/10 and cant wait to play it!
