How about training MMA if you want to get good at MMA? If you need help in certain areas, then you go to a specialist.
How else are you going to learn G&P? In BJJ? How about takedowns while being punched? In wrestling practice? How about learning to time a strike when someone is shooting on you? In boxing class?
You guys complicate a simple thing. How fucking ironic is the statement “jack of all trades, master of none” when you are trying to master 12 different arts, instead of one. You’re trying to be the “jack” of wrestling, boxing, muay thai, BJJ, kickboxing, capoeira, Tae Kwon Do, and Judo and think that all those parts equal the hole.
Stop trying to be the master of 12 arts - there is not greater way to be a jack of all trades.
Break your training into areas: stand-up, clinch ground. Always allow striking, always allow wrestling and grappling. Put it all together at the end of your training session in MMA scrimmage matches of varying intensity.
If you want to get good at something, do that something. Hoping those parts gel together into a whole is absurd - changing the tiniest of variables changes everything as is evidenced by lawn/clay courts, softball/hardball, pancrase/MMA, ring/octagon, etc.
Problem is that people are like traditional martial artists they make fun of so often: stuck in their ways, worship their sensei/coach like a cult leader, bring up lineages, can’t think for themselves, would rather be told, etc.
Flame on crybabies. You’re gis are useless for anything but mopping up spills.
