I don't think we have much room to talk when it comes to being "Obscure" lol. I don't particularly care for those characters myself but I can see the appeal of them and why people would want them in. Envy accomplishes nothing but to make us look dense and oblivious in regards to our current standing. We should try to make fans of other characters also want to support us and vice versa. Then if Arle somehow does make it in fans of other characters will be happy for us rather than upset that their character didn't get in.
Even in the Sega sphere, we have "competition" with other characters. Eggman, Kiryu, even crazy outside picks like Miku could slide in. We gotta be prepared but also support where we can. It's important to remember that Puyo Puyo's resurgence as itself is fairly recent and the characters may be known to fans but not necessarily to non-fans (who would only know the Puyos, if that).
