Every BD class is either trying to lead, get information or help someone else do those things until late game. Any class that cannot do any of those is wasting their time. Occupying/redirecting someone does not help you lead and it does not give you information. Knowing if someone is occupy immune however does.
Note: This is not true late game where you need to actually do something with that information you got from your ability’s and the claims of others. Once you hit a critical stage in the game ability’s such as Drunk HH and Butler occupying known targets and Noble using PP become more valuable for what they are. However giving the ability to work as a psudo invest gives them something to do in the mean time.
