Not having redirection show is an absolutely appalling idea in my opinion. It’d make it just cause complete chaos for BD. Investigatives would get thrown off immensely, physicians can’t reliably check poison/bleed claims anymore either. Knight claims have no way to justify why their guard did not protect that one person, not knowing they have been redirected. The best strategy for Drunk/CW would turn into never using Deb/Tornado anymore.
If you don’t show hitting an immune to the Butler/Drunk, it will make them feel a lot less fun to play. Let’s say there are no deaths n1 and you have hit an occupy immune. You’ll do the same action again even though it’s useless. Even though you make the correct play, you have no impact. The question is if the health of the ecosystem of balance is more important than keeping Butler/Drunk fun.
