Hitting more than one opponent

Instead of a specific Edge like Sweep a mechanic that takes extra damage that is wasted on one enemy automatically to the next one seems cool with exploding dice.
Sure you can install this as an edge too. That way it really makes sense to hit an enemy in the 50ies region...

The same can work with trick mechanics.

Another question is what to do with real high hit results. Instead of not using them, they could be seen as straight damage. This raises the question if a second damage throw is really necessary.
For sure it creates a bell curve in the damage. You have to hit twice really well to do huge ammount of damage (or at least the second time).

As we see this mechanic is only somewhat implemented anyways. A logical conclusion would be to get rid of the damage roll.
