I wouldn't mind this. Some thoughts:

1. It will lead to more accurate valuation of edges. It's possible some edges may become much more popular. Edges taken 90+% of the time by eligible characters should probably get more expensive or suffer a slight nerf. Edges taken <= 10% of the time by eligible characters should probably get cheaper or be juiced slightly.

2. If an edge's functionality is nerfed then a character with that edge should have it removed and get refunded whatever points he spent on it. If h still wants it post-nerf then he can re-spend the points and take it again. Or, he can spend them on something else.

3. I still think we should tweak how EP are awarded. Realize that's not what we're talking about here and that the relevant party has zero desire to further mess with EP calculation, but wanted to say it anyway. Think my philosophy is on record in an old post somewhere.
