I remember reading patch logs about how hosts should be careful which options to give that role because of how powerful it is, but I really don't feel like she's any good. As far as I can tell, her entire purpose is to die while copying a role and mislead town into thinking mafia/triad still has an extra remaining member, right? However, even if you actually pull it off, it has very little impact on the game, besides causing a little confusion concerning claims and the remaining roles in play. Town will just kill a mafia one day and then quickly assume a diva/actress must have died earlier when they see no more kills are coming, and just continue playing (if game hasn't already ended). Am I missing something?
In my opinion, the role copying aspect of the role is the interesting part, and should probably developed. She could use charge(s) to learn someone's role and actually use their ability the next day/night, with the faked role on death as a potential extra rather than the main feature.
