Just curious then, what are you supposed to do if you win a belt in a lower org? I hate pissing anyone off, but I guess it seems like you have to since everyone wants a shot at the belt and you can only do one at a time.
I haven't won any belts yet, but my rule would be "top 5 fighters get shots if they won their last match while I was winning/defending the belt. Ranked 1 gets first offer if won last fight, if not then the offer goes to ranked 2 who won their last fight; if not for 2, then for 3, and so on and so forth."
It's the only fair thing to do. Rematches need to be earned, not handed out, especially for a title that others are fighting for, as well.
