War paint is a great idea, there just needs to be an array of options to actually use to differentiate characters identity from one another. If there are only like 4 paint options and you cant choose the placement, then there might as well be no point. The same thought process mostly applies to other areas, such as Tusks, bone necklaces. Body scars, metal staples to hold an old injury closed, metal plates bolted into the skin to cover exposed internals.
