The point fighting is an issue right now as well, as you've mentioned, but I don't think that it will lead to more, as people who fight cannot count strikes at the same time, they busy with survival and other shit.
I think that those who fights now that way, will probably do the same, and those who aren't won't bother with the new system.
Regarding the kind of strike, I do think that you can qualify the strike to points, but that to be determined. For example it can be decided that a KD is 5 points, otherwise a strike to the head is 2 points, to leg/body - 1 point.
I personally don't think that it is matter how hard the strike was id it did not bring a knokdown, so for me to score it the same, BUT I'm not the one to decide, and that's exactly is my point, that it would be great if someone who is more qualified than myself will decide it, and will point each element,
