The guilds I listed had decent rosters, I didn't care if they "were just having fun" if they tried to win I put them in the category of competitive guilds.
But yeah your right, no one really was hard for the mixed team, can't speak for the idevs because I wasn't in it but I don't think they found it difficult either, even if the teams sucked it's still competition, we can't just say "there was no competition because we are just so damn good"
