Training has been diluted, couldn't agree more.
Here in Canada, there is still a demand for the high time instructor, so it's not a critical issue yet.... Those who justify 300hr pilots teaching 20hr pilots have no idea; either they've never experienced good training from experienced teachers, or they themselves have come up through the ranks of the low-time instructor and are strongly biased.
How can those with no experince operating a helicopter impart knowledge in excess of the federally mandated standard(which sucks in most cases)? Answer: they can't.
