This is what I think. I think the higher calibur fighter that dont have a large payout for fights have higher incentives. Those, like Robbie, that have really high payouts dont get those incentives. I think that with the incentives it ends up being more than those that may not opt for incentives.
By incentives I mean the extras that fighters get paid behind the scens or maybe a cut of the gate or PPV.
I against I,
flesh of my flesh,
and mind of my mind,
two of a kind but one won't survive,
my images reflect in the enemies eye,
and his images reflect in mine the same time
