Gonna shoot this one down right away. Alice, I appreciate you being considerate and wanting to give mafia a bunch of free info to compensate for no daytalk, but never-ending kindness is not always the correct solution. The only time I can remember early claims being useful are instances where they happened selectively based on the power and provability of a role (Lechen's claim in ToS comes to mind, a lot of things went wrong in that game but he wasn't one of them). The shotgun approach doesn't have much actual benefit to town, hence why nobody ever takes up M2H on his D1 massclaim suggestions.
Unless by "character" you just want us to claim flavor... which is kind of a nothingburger?
