So, I managed to get all 8 personality types, including an extra Peppy and Lazy villager. However, I always wondered if you have any benefits of having all personality types represented on your island? I heard it helps you to get all reactions together (not sure if true?), but for what else is it helpful (besides reading different dialogues)? I'm thinking about to replace Gala at some point with another villager who's personality is not a Normal, but before I'm gonna do that, I just want to know if I should maybe keep Gala first a bit longer in case there are benefits where she can be helpful.
