Thank you for your replies, people. It might be a suitable moment to start the tournament in May already, if we come up with some decent ideas. Although I created this thread, it doesn't mean I'd be volunteering to held the tournament alone. Anyone who has experienced a few tournaments already and knows JJ2+ well, can now sign up here more, or less officially.

I sort of agree with you about the tournament-type being either 3vs3 or 4vs4. Should it be clan or not, each team should still have more than the minimum amount of players to have a better chance for all matches to be played.

As soon as possible I will start a poll, where you can vote for your favourite gametype of the possible team-gamemodes.
