As one of the people complaining about too many humans in the party and expressing joy at the thought of being able to play as a "weird race" or having "weird race" companions, I wish to add something.

By all means, I agree that "special" characters should be a drop in the ocean of normies. But I'd say it's enough if the world is the "normal" backdrop; like that human fisher's village. (And yes, we do need more normal backdrop.) Our party could be the band of oddballs.
Then again, as much as I like "weird" characters and would love a whole party of them, the best scenario would be a mix of companions, the whole spectrum of "weirdness". That way you can either have a party of exotic weirdos or a party where weird and normal play off each other - contrast can work amazingly for party dynamics or highlighting the weirdness. Either by having one "straight man" or one "what is this even". Or a more or less even mix. (Or you could have a party of normies if that's more your thing. :P )
Moreover, boring and strange could mix even in one character. Like you have Minsc, a "boring human" with a personality that's anything but boring. Or Aerie, who is an avariel and... your typical wide-eyed naive girl with a sad backstory.
