I agree 100 percent,that what used to be done 20-30 years ago was as real as reality based stuff is today,although we trained hard against similar foghting styles.
(most tMA's covered kicking to punching range,others focused just on ground,so the inclusion of all ranges is beneficial to a point today)
I trained in Hard TMAs that trained to fight hard for the street and for a sport aspect and some included scenarios that showed what truly worked for you ,the participant.
(I was able to this training for many years and used them successfully on the streets as a teen in New York and into adult hood)
Today though due to insurance restraints many arts have watered down their teachings to the point that what they see in RBSD does create a WOW factor,though there are some TMA's that still train the old way and realism is still intact.
Pressure testing is needed today to test what is being taught because aside from sport competiton most do nothing more as they are taught sport and reality are the same thing.
There are many who still believe they will be able to kick a knife out of an attackers hand,obviously they have never actually tried it against an intent ,non cooperative,partner.
Many believe they need to engage in an exchange when in a street encounter,this also is not wise,as the street encounter needs to be ended as fast as possible,you do not kick ,punch move out and do the same over and over.
Many who train in MMA/NHB/BJJ have an idea that all encounters need to go to the ground as fast as possible,this is also not always a wise tactic as the ground should be a last resort place to take a street encounter.
Pressure testing,Hard training,reality training what ever we call it needs to be done either directly in the TMAs or in some training outside be it RBSD or with a partner who shares the need to find what actually works and is usable and to minimize their tool box of employable options.
Just my opinion.
