Ok, but why would 6-player teams discourage a CAL team from coming? This is afterall, a LAN Party. We're not part of CAL, so there's nothing that happens at our LAN Parties of any consequence to CAL standings or reputation or anything. We game for the sake of gaming and good fun.
I know in the past we've had teams come in and think they were going to wipe the floor, end up losing in the first round to a clearly superior team, get ticked off, and leave after only a couple of hours. There was still 35+ hours left in the LAN and they just packed up and left.
That is a completely wrong attitude to have coming into a FITES LAN. We are first and foremost about having a fun time; always have been. Secondly, it's getting to meet other people you have a common interest with (gaming) and maybe finding some new friendships out of the whole experience. That's also where the 6th person on the team comes into play; it may be someone you pick up out of the PUG pool to fill the 6th spot. Maybe that 6th person ends up making a critical kill or score that pushes your 5-man team over the top. Tournaments, I think, come in a distant 3rd to the other two, not because the tournaments are insignificant, but because the fun and camaraderie are just that far up the ladder.
