Unpredictable element in battles come from your enemy taking actions, not from RNG where you go into a fight with a half loaded revolver, expecting it to be a russian roulette. When you go into a fight with a revolver, you darn well do everything to make sure the gun never jam and load all the bullets into it. To do the opposite is just idiotic.

This is something that was brought in my the new Ini. Enemies taking action and making even well crafted plan fail unless you find a way to remove this uncertainty with good delayed turn or targeting the right enemies.

Don't give people jammed and half reloaded revolver if you want a tactical fight.
