Why I can't host a Command & Conquer 4 TT game, and nobody can

I still don't get it. Why C&C 3 is working online and C&C4 not. Generals is more than laggy over online (so I'm playing it with tunngle). Can they just make a patch to host like in C&C 3 and let us play the game? Just don't know what they want. I'm feeling sorry now that i didn't bought the hard bundle of C&C insted of Origin (same price). That way a would be able to play at least some of the games offline in single play, as i don't see a bright future to Origin.
