Kell, apologies for not having read the entire thread before posting this (and I will go back to read), but have you considered points for 'failures'? As a gamer, I hold we learn more from what we fail to do, than what we successfully do, as that failure leads us to try harder, explore a different angle.
I understand introducing failure points without modifying the existing point system would create too many opportunities, but it seems to me that a force -whether or not it is victorious by any margins- would still have the opportunity to improve because of the experience of the battle.
Just throwing this in there for conversation's sake, as clearly the rules as you wrote them are easily house-modifiable.
Thanks.
Also, you might want to go back and fix the Initiative post above to show the "50% or more".
