The archer stunt is using a play off an existing ability method that I recommend as a quick and dirty because it starts with a well defined ability --- when a game has well defined abilities adjustment or bouncing off of those is much easier on me. I feel like most skill use just doesnt.
Even barring that specific example, I believe that if a DM is doing their job the adjudication of the rules (whether using an ability or any other ruling) will be fair and as consistent as possible.
That, and I don't think we need to give all characters supernatural abilities in order for them to contribute. It's never been an issue in any game I've ever participated in. Do some people hog the spotlight? Yes, but they do that no matter what the build.
