i love kyokushin but the rule set is bananas. "Flying knees to the face? Sure. Head kicks? Absolutely. Leg kicks? Yessir. Punches to the face? Let's not go nuts here, better to stick with body punches."
It depends on your definition of bananas. For me bananas are nice and sweet, just like Kyokushin
I don't see how you could possibly legally fight bare knuckle in this day and age otherwise, unless you're fighting in Leithwei which you can pretty much only find in Myanmar.
Also, the fact that you can't punch to the face means you have to rely on other weapons to KO your opponent, i.e body punches, knees, kicks etc. This makes the sport a lot of more technically skilled.
Somehow you also really limit the amount of brain damage you accumulate through the years, compared to let's say boxing or MMA. Granted you may get knee'd or kicked to the head, but how often does that happen compared to when full force punches to the head are allowed?
Some Kyokushin / Knockdown guys would also argue that it's stupid to fight with big padding on your hands, as the way you're punching with gloves is unrealistic - you don't have to form a proper fist and keep your wrist straight, and you also tend to hit a lot harder when wearing gloves as your hands are protected than you would without them - and blocking and protecting your head with big gloves is also unrealistic.
At the end of the day you have to appreciate it for what it is, and if you don't like it don't watch it. I don't comment on wrestling or BJJ topics for example as it doesn't interest me.
I think Shidokan have it right as they do Knockdown, Kickboxing/Thai Boxing, and Grappling
