I dislike how they removed LAN plan from the game, you can still play multiplayer but you have to link up through the battlenet servers, I mean hello LAN parties were made so you didn't have to worry about outside connection, that said not that big of a rub on me because....
I really hope the single player aspect is there because I loathe a lot of multiplayer action on games like these, where you don't get a chance to think about what to do you just have to go like a robot and follow a "pattern"
