It's different though (for me at least). Jon Jones defended his title like 8 times? He proved in the octagon he is a different beast, the best light weight by far.
Getting to the top is easy, staying there is the hard part.
I doubt any MMA fan would even consider Conor over Jose Aldo in an all time ranking of the best fighters.
Hopefully Conor starts defending his belts, or retires, so the sport can move on.
edit. I think i might have misinterpreted your point. In both cases, its the UFC to blame i think. They have no idea how to deal with their top draws. Anyway in both cases too, its gonna be fanboys the ones who gonna talk crap and undermine the current champions. The rest of us MMA fans, we just want for the divisions to carry on.
