I’lll taaaeek yoooo hooooooooeeeem, AGAAAAAAIN KATHLEEN!
Just being in Starfleet in general, honestly:
I feel like they could have done several things to make them more realistic.
One option might have been instead making it a form of matterless telepathic project, with a bunch of the crew having to awkwardly walk inside these projections.
Another option might have been to make it so the Doopler behaves sort of like a replicator and uses materials from its environment to build clones. At first, the Cerritos life support systems would be able to keep up, but then, instead of the risk of being crushed, it could have instead been the risk of oxygen depletion or something as life support struggles to keep up. Granted, that would have made beaming the Doopler emissary onto the star base even more sadistic than it already was, so you'd have to find a way to revise them.
I feel like the Pandronians aren’t as severe - maybe an 8. You could explain the floating in part as a naturally occurring anti-gravity system (which does canonically exist artificially).
I might be biased, though, in kn my Star Trek Adventures campaign, I have a Pandronian as my chief medical officer.
I feel like as this goes on, this list just devolves into random Star Trek species.
I mean, the whole point of the Antedians and Breen is they’re total meme species.
I personally feel like one of the ACTUAL worst species in the franchise is LD’s Dooplers. While overall, the eponymous episode is great, probably one of the series bests, the Dooplers felt out of place. Usually, Lower Decks has a standard of doing things that are both ridiculous and plausible by Star Trek logic - in other words, the cartoon dial is usually set at 6 or 7 (unless it’s a hallucination), but I feel like the Dooplers were a jarring turn to a 10.
Me, in Arizona: 
Though honestly, my thought is if the rest of the country gets rid of DST, I feel like Pacific should go to PDT because it’s incredibly nice when that part of the country aligns with Arizona’s time. Granted, that might be weirder for the eastern Mountain time states.
Oh, my gosh. Weyoun is so beautiful! And you can make him smile! Now all we need is a Lakarian City playset... a pile of ash should do.
But what about Okana at the Starfleet Command Party representing our acceptance:
Or much less attractive PRO Okana, representing the season 3 theme change?
Just give us Prodigy S3. Granted, we'd have to see how they work it out, considering they've hit the Picard era.
Maybe we could just have a little "accident" where Admiral Janeway is visiting the Protostar when they all get whisked into the 2430s and can't return so they don't have to deal with Picard crap. It wouldn't be as radical of a future as Discovery - we'll just have a nice, peaceful era with only the occasional threat.
The Protostar has some new worlds to explore, while Janeway struggles to reintegrate into Starfleet and catches up with her still-surviving friends, probably including elderly Mr. Tysess, Tuvok (who, even with conservative estimates, probably still have 3 decades ahead of them) Chakotay (probably not in as good health as Tuvok or Tysess, but holding on), as well as the Doctor.
Besides potentially being able to do TNG monster of the week, you've got at least 1 free episode plot for checking in on Solum. Besides having some plot on thea now non-destroyed Solum, we could have Ilthuran's reaction to being reunited with Gwyn after decades as well as, at a minimum, a bit of comedy from a nice, non-fascist Ascencia (It would be even funnier if this Ascenscia at one point became a legit Starfleet officer).
Give us Prodigy S3, please.
Actually, that was Barenaked Ladies that did the Big Bang Theory theme. Totally different guys.
Currently running a campaign on 1st edition. May look into this.
