Lol you noob...it's called MMA.
Very few belts in UFC are with pure wrestlers.
You just mad that khabib won.
Maybe OP is no noob, maybe you are?
This already HAS happened.
Wrestling and BJJ already did get cut back. You see standups, so if you're going to say "noob" and "mma", then you don't know how it all started. For fuck's sake, we even got standups out of sidemount.
Rounds: Didnt exist and were a clear advantage for grapplers. No clock will let you stand up and catch your breath, after being blanket fucked for 3 straight minutes.
Then let's go further down the "MMA, you noob" line. Muay Thai: Elbows: Not all of them are allowed (12-6). Knees on the ground (if you want to fit that in MT): Very restricting rules. Kicks on the ground: Same thing.
So dial it back a bit. Modern MMA has had SEVERE restrictions done, all so that the real noobs like you, would find it enjoayble.
