Rules on defence of belts. And, guidelines on who a champ must defend against.
A healthy champ MUST defend twice per year. And, must defend against the highest ranked fighter that makes sense. Of course injuries can affect both of those things. And, can be reviewed on a case by case basis. With some kind of neutral arbiter to assure fairness to everybody involved. If it’s actually needed. But, it really shouldn’t be necessary, imo.
To the best of my knowledge. The ACs have no say about either of those things.
But, they need to get their shit together, and adopt the new rules. One AC doing it this way, and another doing it another way, is pure bullshit.
Of course if everybody uses the new rules. There can be deductions much easier. If the ref enforces the rules. And, there should be more 10-8 rounds. But, that of course, is on the three blind mice.
Other than that, I’m pretty good with most everything else.
EDIT...
Legit fuckin rankings are necessary, too.
