With the current model, a PW is like a blackout ie, loss of blood. In WWII the closest things to it would be a G pull that blacked you out, or you went in and out of consciousness, more though, you go in, but don't come out. Many places that would constitute damage that would kill you as fast as current PW's do, would leave the pilot incable of combat anyway.
I'd like to see a degree but it would also take alot of programming. Like a hit to the shoulder, blood loss yes, apply pressure on the ride home and you'd more than likely be fine, where as no matter what you do now, you die unless you make it home very quickly. If it causes a blackout state.. you should either be dead, or have massive flight compensation to work on. I don't know all the details that would be needed, and I expect it to be hard, but I dislike the current system and this is kind of my take on a better solution... BUT the current system is here, and I won't complain if it stays the same either.
Sorry if thoughts seem muddled. I can't make myself happy with putting them to text.
