As I play SP, I find I have to crank supplies up to 150% just to keep AI armies from starving to death.

Air bless needs an overhaul, but if charge body is to be used, the units need to get the shock resistance anyway, because the charged unit will also take damage when the effect is triggered. Unless it has resistance, that is. The copper plate armor actually gives both 100% shockres AND charge body, but those are separate effects.
