Name 10 of these gyms in your country that turns out high level MMA fighters w/o employing Muay Thai.
What on earth are you talking about? I don't actually think you are following the same conversation as we are.
Change that to, there are more fighters produced...in MT/BJJ/MMA gyms.... to fight at the highest levels of full contact, combat sports; with the highest being The UFC.
This is what you said, I told you then your sentence doesn't make any sense because all you are saying is these gyms turn out fighters, which as I said is their job. Where do you get this thing that it's without Muay Thai. Of course the Muay Thai gyms turn out Muay Thai fighters, how would they train MT if they didn't do it?
Many gyms train 'striking/stand up' this will be a mixture of techniques that the coaches find works, they can make it so that training is personalised for individual fighters, or they can make it general for a class. It's not 'pure' anything, some coaches come from a MT background, some form boxing, others TKD or karate, they mix up their techniques to find the best possible outcome for their fighters.
One of the things I like about training MMA is the 'looseness' of techniques, being smaller and lighter many techniques from traditional styles which have to be done for gradings etc have to be done perfectly, in MMA you can tweak, play with and manipulate techniques until you make them work for you. On a figure four arm bar for example the strong men with longer arms do it one way, I've been shown another way that makes it work better for me, there's no 'perfect' way to do it that's going to be judged, if it works it's a winner.
There's no 'pure' MT in MMA just as there is no 'pure' any style, we change it, mould it until it works. We do it all the time to all styles so everything we do in MMA is as effective as we can make it. In this respect many styles that have standup are just as good as MT.
