For the Women: Do want, and if you have seen their fights in Invicta you know exactly why.
For the Men: If they open up more Asian and Central/South American markets then those will be fantastic divisions. But as of now, nope.
I say no, and here's why. Those weight classes are almost predominantly dominated by Asian fighters, who generally tend to be smaller. The UFC can't market that effectively.
You'd think the Asian market would be a gold mine for the ZUFFA execs with the lighters guys?
I'd assume not too tangible in the West though.
Not right now.
I actually think that they should take 125, 135, 145 , 155 and find a way to make it only 3 divisions (130,140,155)
