I like injuries system a lot, both the idea and the way it is implemented.
But can we have more different perma injuries that do not completely cripple the soldier? Losing 30% of melee attack/defense is usually the end the journey pretty much for any veteran. I also like injuries that decrease one stat and increase another, like brain damage. Also would be cool to see some veterans to learn to decrease the impact of the injury (like only 10% penalty instead of 30%).
And can treated injury have only 50% stat penalty?
