Is an all or nothing equality situation.

Everyone gets the same amount of edge points, and edge points are given a numerical value like thief points are.

Then you unlock edge points as you level. The first at 15, some every 5 or 10 levels after that.

Easy system from there. Everyone gets the same amount of points to spend but you can spend them as you level and see fit on edges. Everyone gets some edges and nobody can complain about an unlevel playing field other than gear, which is part of the game.

Only thing needs to be done is figure out the numerical values of what everything would cost and how many edge points you got at what level.
