COD4 is just mental on PC with servers that size, the maps just aren't big enough for it and all you end up with is a massive scrummage, a million airstrikes, and constant choppers.
Some people like that though and that's fair enough, no need to remove the choice.
It's dumb to take away servers, they could have left them in alongside the new matchmaking system and given people a choice. Now everybody has to put up with host advantage.
Not the thread though, plenty of places to moan in the PC forum.
