You need to fix client stability first, i'm not repeating a tournament match 10 times because of crashes. After this, the gross imbalances need to get fixed. Then i'd be interested in doing a tournament.
1. Make sure you didnt torrent the game.
2. Make sure all your software and hardware is working properly.
3. Send your exe file to ironlad to see if its corrupted
4. This post is just not the right one to post about your problem.
Ive been playing this game since the beta, and this have been one of the most stable games ive ever tried. And the imbalances is a matter of opinion.
