Its odd seeing the stark contrast in people that like WWE and MMA. I love both and my friends would call me a chameleon (fit in and get along with just about anyone) but seeing the cross promotion IMO doesnt help either brand largely bcuz wrestling fans are fantasically,nerdy, and occasionally a bit off mentally. MMA fans for the most part are opposite types bloodthirsty, jocks, drinkers, and for the most part regular type of people.
I dont see how the wrestling fanbase comes over to MMA cuz they feel like the kids that got picked on by the jocks in school growing up and like to stay in their "corner" its a weird and half-baked idea but Im not sure the TKO brand promoting both on their platforms is helping as much as they think it is.
