The main problem as I see it is as Rei pointed out and that the KT orgs and Grappling orgs usually fold up because there just aren't enough fighters that are that specialized. So you fight the same three fighters over and over again, get bored, leave the org and after a few events the org has no one in it so they fold. There is a possible fix here, but I am not sure how labor intensive it would be and whether Mike is willing to even invest the effort into something like that.
There would have to be an incentive. Maybe Boxing orgs gain moire money but gain less hype.
