My point still stands.

They should have use a lobby based system like that of TF2 with the addition of an option that restricting the game to a specific levels above, equal, or a bit below yours, though you cannot play with someone of a significant level below with out their consent, and also the ability to search for players of a certain level group it you so wish, with the same rules above.

So you can chose what match you wish to join manually or you can get the computer to search for a certain skill level around or above yours, kinda like the system now, if you so wish.
