I used to heal others if possible. Because, why not? It only cost you 3s of time, and get +15 scores.
And I might see that healed soldier (which is controlled by human) thanks my by Q/E or jumping. Funny to see others reaction after being helped.
But even back in the days that healing others has no cost, still NO BODY cares about healing others!
Then one day, I found after healing others, my medkit was gone. And I can’t heal myself.
After that, I NEVER heal others. Since most of my soldiers only carry 1 medkit! If I heal you, then I will going to die.
