Sadly, nothing will change with the glitch cheaters. Best thing to do is remember their names and quickly bail if you see them.
Sadly, even with high speed internet, I always seem to end up in the blue corner against players whose obnoxious styles are based around exploits.
Sadly, the franchise has been at a point where it just doesn't care. Look at the YouTube community from ufc 3 and look at it now. 80% or more of the creators from that time quit the franchise entirely. There was genuine interest and hype back then. The view counts don't lie.
Ranked mma and online career have their own glaring issues -- after the first week of a season it just becomes a frustrating cycle of running into the same few people, the same horrible yet rewarded meta, the screen glitch cheaters... on and on. I proudly have never played stand and bang because... well, I can't say why because my reasoning likely violates ToS.
Bottom line- I love MMA and the game can be fun when you luckily get matched up with a player who is also a fan of the sport but that seems to be a rare thing lately.
