where did i say boztepe isn't doing mma?
like i said, it's clear to me that you're not familiar with WC... the WCers in those vids are obviously unprepared to face a grappler and make the mistake of making ineffective knees/ kicks when they should just redirect and elbow to the head.

you are making assumptions that all WCers fight like that... some fat white guy (who is clearly not a good fighter anyway, look at how he just loses it) getting taken down and his head pounded does not mean that the style is at fault. your claim that WC schools only train light contact is propoganda, mine certainly doesn't.
in a
real hardcore fight (rather than an artificial fight with rules in a static environment), you have eye and throat strikes, heel strikes to the nose, groin strikes, kicks through the rear leg, breaks from a punch... instant show stoppers. WCs sticky hands is also uniquely suited to training you to instantly react to what the other person's hands are doing... you learn to logically cover every door. once you have contact and are stuck to your opponents hands (and legs) your opponent will tell you through their movements how to hit them, you are on full auto pilot. you also have to be able to simultaneously attack and
defend (the area that kickboxing lacks, good defence) if you want to have a shit show against multiple opponents. i can't speak for every WC school (and like most disciplines there are many shit ones, especially cheung's "traditional" WC which you have used as an example), but I can tell you that my own training has held me in good stead.
