I 100% agree, regardless of what system we take, there will be complaints, loopholes and flaws that will be picked at, and picked at. Yes, some people are very unhappy, because their stats have affected their ability to play, etc.
The stats we have atm, listed above simply need a little refining. For instance, I see a HWY stretcher as slow, I see a LHWY sub guy as somewhat nippier than a showman. Ryder should not be grappling at the speed of, for example KD. KD's a big guy, who bends you when he grabs you, his pitfall for picking Stretcher should be SLOW and not exactly high tech.
Ryder's falling for Sub, one would assume, would be low charisma and low grp+str? His submissions are how he causes pain, that should be his strong point.
Power would excell at damage, but be slow, and probably not very charismatic. I'm aware there's exceptions to the rule, but things need generalised.
Brawler should take damage pretty well.
Again, these are all opinions, but it's a never ending circle.
