1st rule of PUG fight club...
you don't QQ in the lobby about teams.
It's getting old. I like to do a rough balance and go, not listen to the "but he has .001% higher ratio! This is SO UNFAIR!"
...or worse, the pre-mades that are missing one and cry their ass off until they get a good player, then proceed to team-play stomp the other team. The lobby time lasts longer than the game does.
In fact, the lobby times are, generally, lasting longer than the games. You wait for players, try to balance, cater to the whiners about that extra 2% difference, have the pre-mades who stop by and ask if we all can move around so they can be on the same team, leavers, more people jumping in and start the crying all over again...
Maybe start naming games "WILL WAIT 30 MINS FOR ULTIMATE BALANCE!" or "PUGs LOOKING FOR PRE-MADE TEAMS!", but "Quick game" and "We got hookers!" probably implies it's going to be a quick start, rough balanced, play for fun (it is a game, afterall).
If you're THAT worried about your win/loss ratio... give me your address and I'll send you a men's health mag and a protein bar.
