Having led a TOJ competition team in the past (principal members were Killerah, Shagz, James, myself, and ColdSteel), I am unfortunately kind of burnt out on the prospect. We had a lot of fun and did pretty well, but eventually we fizzled out due to lack of available time and interest. With UT3 due soon, I don't feel like the dwindling UT2004 community is the proper climate for new competition teams. I know though Tea, that you're really eager about giving this a shot. I don't predict that there will be enough interest for a full 4v4 TDM team but if you want, catch me on Xfire sometime and we can discuss doing a casual 2v2 ladder thing so you can get your feet wet, so to speak.
Plus, in the UT3 leagues, if it comes down to playing for TOJ and playing for LOB on a given ladder, I will have to play for LOB... not because I like them better necessarily, but because, when it comes to competition, they have to have a higher claim on my time and effort. I joined TOJ primarily for casual social play with likeminded people, and I joined LOB to compete and excel. If, when UT3 comes out, TOJ decides to play on ladders other than the ones LOB plays on, then I'd gladly play for TOJ, time permitting.
