Anything that brings fairness for both sides is a good update. I haven't played for a while, but as far as I know, danger level is a standard measurement (as soon as accepted the suggestion about afk cops) in CnR, so basing a suggestion on that is already an excellent idea.
Just as some said above, I think that danger level 1 means that CnR is balanced, and the MPCC seems kinda op in this situation, using it when "balanced" would bring an "imbalance", no?
