All my villagers are low tier. Chrissy and bob are tier 2, jacques used to be tier 3 but i believe he is tier 4 now, everyone else is tier 5, except phoebe who i dont know where she goes. Tier 5 probably. Yeah, love my lower tier villagers. All of them are sweethearts.
Phoebe is tier 2.
I don't really think people should hate on villagers because they're bottom or top tier.
I hate villager hipsters personally. It's your choice which villagers you want, and you shouldn't have people going 'ughh, trust you to go with those top tier villagers'.
I wouldn't trade out my villagers for the world, no matter what tier, like FlitterTatted said.
