My problem is: The community of WoW constantly complains, and is never satisfied with anything. It's really disappointing to be honest. Blizzard works so hard to improve their game. They didn't really have to improve the models, but they did, for you. And yet, you're not satisfied? You're not satisfied with them creating a complete new world? You're not satisfied with no new class or race? Blizzard takes a LOT of time to improve the game for us. I feel like it's about time to thank them for all the effort they put through WoW.
Now for the expansion. I'm VERY excited. I think it's cool we get to go back and see how the Orcs and Draenei lived, and how they fought. What's also more interesting is seeing how the Warlords interacted with each other, and how they will react to seeing people come from another world. Also the new models are VERY amazing. It makes me want to roll EVERY race.. I'm really happy with (though it's still in the making) this expac.
