Mook Rule
A thought just struck me, while considering the street level heroes.
Let a superhero fight as many ordinary people at once as the number of ranks of Fighting above Poor they have. So 5 for Daredevil, 6 for Captain America etc., assuming they are all adjacent enough.
To make that harder or more appropriate to fighter-heroes, a bonus part of Martial Arts.
So Daredevil could roll to hit 5 thugs that had piled on at once and punch/kick/elbow or whatever all 5 of them at once on a green.
