Well the only tournament I am active in is kind of what you are talking about here:
I understand that this tournament is supposed to be setting up a 3v3 euro ladder of the best euro players on warlight. However, there are quite a few teams with inactive players that needs spots to be filled once the tournament ends and the ladder starts. More importantly, although you have to talk to Yuan (or whatever name he is sporting for the next 2 hours) (and assuming that this is ladder was his idea): there will probably be a system of challenges onto the ladder.
Again, if that is the case I would say that why not assemble a 3v3 euro team now to be ready for challenging? I am also interested by the plans of this ladder as well, as a challenge system would be the easiest to get new teams on the ladder as well as have movement on the ladder. This would eliminate a moderator assigning random games and avoid a point based system.
That is all, figured I should make my bi-yearly forum post
