I don't understand why bump is needed it is simple the answer has already been given multiple times.
After more than 5-6 rounds it gets boring.When people get past I say 2nd dan they shift away from the mod completely because
people are focused on mods like ABD taekkyon boxshu etc. Also, most people who wanna box/MMA just learn how to MAS.
So what I would say is go to MAS if you want an MMA experience.
