I think that MMA was a great shot in the arm for all those that THOUGHT they were doing MA in a practical way, it showed that the majority of people can't fight their way out of a paper bag, no excuses.
For those in the "know", that whole "no rules" excuse is and was BS, many of us have actually fought no rules, like thew earlier Vale Tudo matches were, and some of us have actually used our MA skills for real, not in La-La land, and those people will tell you that what does work "for real" is what works in the ring:
Speed, power, aggression, basics.
As for TMA, Since I have always viewed MMA as a step "back" to real TMA training, I don't see an issue.
All TMA have to do to "survive" is brace the core principles of MMA training:
Training with a resiting opponent ( alive training, as much as I hate that word)
Training that covers all facets and ranges of a fight, INCLUDING weapons.
Training with the highest caliber people you can find to see just how well you ARE training.

Praise be my Lord my Rock,
He trains my hands for war, my fingers for battle !
