After reading the dueling dilemma topic i wanted to share my solution that brings the tension back to duels. It works and i know it because when playing my first games we messed up the rules and played dusls differenly which lead us to making them more interesting.
Let us play actions after the bid and before reveal, but only the actions that actually target one of the dueling characters.
That's it, done. Dueling fixed, now nothing is certain.
