,Joy,
You make a valid point.
Perhaps it is like Jim said, we are looking at WC to evolves to deal with A. B or C but maybe it doesn't have to, certainly MT and Boxing ( to name only two) haven't.
BUT I think for that to be the case then WC has to admit to itself ( not that it is an entity but you knwo what I mean) that it doesn't have the solution to ground work ( as an example) and to advocate addressing that problem somewhere else, like Boxing and MT and Karate do.
Psalms 144:1
Praise be my Lord my Rock,
He trains my hands for war, my fingers for battle !
