This is a good idea. A rework would add a sense of individuality and uniqueness to the sandbox aspect of the game. Sure it was annoying but if implemented in a different way like protecting bounties in missions until its over could help balance it.
idea: if 2 bounties are on a map and not in mission, the district turns into a 50v50 n whoever kills the bounty gets a prize or sum. (similar to the chaos mode they tried to release 10 years ago)
