If you hate WMMA, you're probably not going to give a fuck in the first place.
Otherwise, this is a perfectly reasonable title fight. MacFarlane is 5-0 in Bellator and has more than proven herself. Ducote isn't ideal since MacFarlane has a win over her, but that's Ducote's only loss in Bellator and she's only 23, so she should still be on an upswing in her career.
I'm fine with this as an inaugural title fight.
I'll call shenanigans if they try and force Anastasia Yankova or Lena Ovchynnikova into an unearned title shot while benching better fighters. Meanwhile please get Valerie Letourneau and Colleen Schneider some fights.
