On the base of the whole "teaming" rule, it does help the server a lot, although some people completely miss the point.
When 2 (or more) experienced players team, they will usually always win the round. Before it was an offense this happened quite a lot. The only way to counter it arguably would to either have another team or teams or everybody agro's on said teamers at the start of the round. Solution #1 turns the server into a weird TDM in the long run, where the good teams will probably win every single round too. Solution #2 doesn't work because either half the server is foreign or handicapped and wouldn't ally against a x2 scale MAS to save their own skin.
Solution #3 is to stop it, this works and although it ruins some peoples fun (somewhat), it keeps most of the regular userbase on, because god damn having 2 forgettards win every round gets annoying fast.
