Pros New stuff, funner questing, easier to earn gold and experience.
Cons everything is destroyed :(
Summary honestly every time blizzard releases a new expansion i get depressed. (but i guess thats my woman genes kicking in.) I started playing when BC was released, and I loved it. And then Wrath came out. I hated Wrath, I missed BC, the lore is what keeps me playing this game, the storyline is just amazing, so well done, and just for everyone. There's magic, love, and war. It's brilliant. I'm not going to lie, the Fall of the Lich King scene makes me cry every time I see it. Maybe i'm just crazy. NOW Cataclysm. I honestly pissed my pants when this finally came out. I was up at 3am waiting for the realms to go live(digital preorder for the win). And constantly clicking to get logged back in everytime the servers crashed. Cataclysm was no disappointment . It was sad to say goodbye to Wrath, and pretty much anything you knew about Azeroth(mostly the landscape); but totally worth it. Kudos to Blizzard for making such a successful; although incredibly expensive, game. If you can even call it a game anymore. I have no shame in admitting, World of Warcraft is like a second life to me; sometimes my first.
