Oh yes I do. The majority of my training was in TMA styles, or at least styles that attempted to pattern themselves as "traditional" in order to hide their glaring flaws. I think one of the disadvantages that TMAs tend to have is that they attempt to be all things to all people. More modern styles make it known that if you want to learn something not emphasized in the style you're currently training in, you should cross train. My instructor for example says pretty plainly that if you want to become good at punching and kicking, then you should cross train
On the other hand, if I were still doing Karate, my instructor would be showing me some half-assed choke holds, take downs, or even whip out some Sais or a Staff in an attempt to prove to me that Karate was a "complete system". I never "really" learned how to stop a takedown or a choke in Karate, but I'm sure that if I asked, my sensei would come up with some crazy maneuver that's never been tested in any sensible or reliable form whatsoever. However, since some Okinawan or Japanese guy formalized it 100 years ago, its still better than those MMA guys because their stuff "only works in the ring".
Like I said, its all the same song and dance. The difference now is that people are realizing the emperor has no clothes, thanks to social media, YouTube, and MMA competitions. For example, if this guy didn't show a Youtube, we'd be seeing those sequenced photos from Black Belt magazine and thinking this guy knew what he was talking about.
