Clearly "bottom of the barrel" was a poor choice of words, as it seems to have obscured the meaning of what I'm trying to say. I didn't mean to insult any characters or series in particular, but rather to make a statement about what we have vs. what is left.
I feel like there is definitely something to adding new series instead of piling on Fire Emblem characters, but...
I think statements like these sort of obscure the point. "Deserve" is such an arbitrary concept, with such arbitrary criteria. 100 more characters could be argued to "deserve" a spot in Smash based on one criteria or another. So my statement isn't meant to say that anyone does or doesn't deserve a spot. If we are going by my personal wants, I haven't actively wanted a character in Smash since Toon Link. The last two smash games have been (for me) just a game of waiting to be surprised by new and interesting characters I didn't know that I wanted.
But ultimately, the roster is limited. The developers cannot add characters endlessly while keeping the quality and balance of the game. The fun of waiting for and speculating about new characters is one half of the enjoyment, but the other half is actually playing, and in order for that to be fun, the developers need to cap their workload somewhere.
So when looking at a limited roster, and a limited number of newcomers, Nintendo's choice to (so far) go Third Party for the fighter pass makes sense to me. It's not a statement that Rhythm Heaven doesn't deserve inclusion, or that Dixie Kong isn't good enough, but rather that it feels time to start going for big names outside of Nintendo rather than Nintendo (further) mining it's own history for the next characters that haven't been added. Characters that aren't considered to be in the top 50 in terms of priority.
That's not to say that new IPs shouldn't get any support in order to create big names. Just that new IPs getting support should feel more like a trade off, where Smash is support, not life support. Inkling makes sense. Inkling is a new IP with a future. So let's use Smash to build on that.
Maybe wording my point that way won't be any less unpopular, because a lot of people in these communities have spent a lot of thought on this and made big emotional investments in these "next characters in line." But too often character speculation is treated like taking turns. After character a gets in, then chaacter b is next. After p, then q. I think there is value in letting ourselves be surprised. In accepting that a character doesn't need to get in just because a vocal minority of Smash fans have been pining for that character long enough.
I like the idea of getting characters we didn't know to ask for, instead of characters that are simply next.
Toad is in Smash.
