As if the heavyweight talent pool wasn’t shallow enough, they add even more weight classes to further dilute it.
They are following the boxing model. More champions in less competitive divisions.
It’s all about the money. Title fights pay more and now there are more titles to fight for.
But the good fighters just move between a few divisions to go up against either the best, or the most marketable, opponent. The sad thing is when they force someone to vacate one title after winning another. I sat let them defend at any weight they can make as long as they are willing to fight with reasonable frequency to defend each and every title.
