For Directive Tournaments that are free to play, they run with no contest, to give players an enjoyable experience even if the bracket is not full. This allows for a maximization of enjoyment.
In the next big update, however, tournaments brackets that will be played for prizes, that do not have the correct number of players will be cancelled and any credits will be refunded. This way, tournaments can have the maximum prizes for competitors.
With that being said, if you would like to help out with testing the, the cash prize tournament update is current in late Alpha-Stage. If you would like to assist with testing we can send you an invitation to our alpha test track.
