Interresting! I'd like to get feedback from more people before taking a decisions like that, personally. To answer some of your specific points:
- Scam, Scamilla: that's the one me and my friends actually use. It's short and handy. Never seen any actual use of playboy camilla though.
- Naked Xander: same, me and my friends actually use it. (Nothing to say about Wonkander).
- Brideload: true. Still somewhat clever name.
- Mike: Eh. Neutral on that.
- Greenzura: Good point. I should remove it.
- F!Grima or M!Grima should be enough for reworking: fair point. I still mostly use Grimair myself for FGrima.
- Fakumi: what's wrong with that? I don't understand what you say.
- Flagger: I dunno, I like it, even if I agree it doesn't seen much use.
- TotallyNotLucina, LuciMask, Flat Marth : I agree I never much liked all those nicknames for Lucina.
- Sakakitty: It's not great, I'll give you that.
- Mery Miss Axe: Faintly funny puny name, but a bit long.
- Awww I like President Eliwood but I love bilingual puns.
- Coy ain't great, yeah.
- Berserktor is pretty good even if not as much used as Vector or Hunktor.
