Ya so I still haven't committed rule to paper about the whole starting HP thing. I am even less certain about the whole taking stat damage when you have no agency. I like the ideas but I see them taking the game away from a d20 realm and into other directions. I mean hit point in D20 are pretty flexible and can take a lot of abuse - point being that you can play around with player hit point progression wildly and still recognize the system (although as D&D went along it did become noticeable that something was happening here.) Still I think having HP bypassed so easily could be easily abused or misused.
I hope I can get in some play-testing again soon because I think these ideas really need to be worked through in the field and run by some players instead of just percolating on the blog.
