I do live on a college campus with provided internet, but I have never seen it block a game. It does block p2p downloading, but i'm not sure if that would affect signing into the game. It not my connection speed either, I usually sit right next to the router and get 3 mb/s download speed.
I just want to play this great game, and am really anxious. So if there is anyone out there who can help me with my problem, that would be wonderful. Blizzard or otherwise. If more information is needed I can provide that as well.
