I don't like how Edge works in 6th edition. There, I said it (I guess this must sound like a broken record to some by now).
More precisely, I don't like how you accumulate Edge on certain actions that you can then re-use later on other actions that have absolutely nothing in common. Like you dodge and soak damage like a god, thanks to which you can then suddenly unleash a powerful matrix action.
It's not even there to reward good roleplaying or smart ideas, like for example when your characters recovers Willpower when acting according to her nature in Vampire the Masquerade. No, it's purely mechanical (and boring). Sometimes you even have a guaranteed Edge gain in some circumstances thanks to some qualities. I had a character at my table that was replenishing his Edge just by being attacked and was even freely giving Edge points to his teammates (there is an Edge use for that).
I liked how in previous editions the Edge attribute really represented a character's luck. His potential to "bend the rules" a certain amount of times during the game. His get-out-of-jail cards. Now it has just become a resource that gets used-up and replenished all the time, provided that you have the equipment/qualities/stats to consistently "get the edge" over your opponents.
I didn't want to derail the houserules topic specifically for that, but I was wondering if someone like-minded had good houserules to propose to rework the Edge system?
