World of Warcraft new expansion? I need your opinion!?

personally i hate the new expansion mainly the fact that you can get mounts in azeroth it will be so easy rading the horde or alliance that way. And dude also i dissagree on what you said for the levels if you play battleground called Alteric Valley you get 19k xp per boss or tower destroyed i got 2 levels in 1 day. 78-80
