Quiver Dance Lumineon (first damn thing I checked for)
Gunk Shot Weezing (my boy has been deprived of physical STAB since the physical/special split itself)
Dodrio lost Jump Kick and didn't get High Jump Kick to replace it. Yeah, it got Lunge, but even still...
And this one is more of a weird decision in terms of the Pokémon's lore than any sort of practicality, considering it does still have access to the move, but... they took Dream Eater off of Drowzee and Hypno's level-up movepool, and then put Hypnosis on there 3 times. Like... after the fandom's been calling them out on Drowzee and Hypno not getting Dream Eater by leveling up even though eating dreams comes as naturally to them as Hypnosis itself... and then after they actually do it, they take it right back at the first opportunity. Like... really? Same deal with Muk and Moonblast- that was such a good pick for it because of how Grimer as a species is said to have come to be, but then they just take it away again...
I don't think they took any of the LGPE learnsets in mind for the learnsets in these games. It seems all to be modified SwSh or USUM learnsets, depending on the pokémon.
As for Drowzee and Hypno, their learnsets suffer from ILCA's reluctance to either shuffle around moves or cut down the length of learnsets. The last slot with Hypnosis is at level 37, which may have been a little early for Drowzee/Hypno, but that could have been easily fixed by moving up some later moves and put in Dream Eater in a later slot. Also, Drowzee's level-up learnset could have easily been trimmed down instead, since it didn't really need more moves (other than Dream Eater) as compensation for those that have been cut. Its learnset is already pretty long (it learns moves every four levels and yet its learnsets goes into the 60's), and Hypno doesn't even change level-up pattern after evolution since the learnset already goes on for so long already.
And as a matter of fact, ILCA did cut lengths of learnsets or shuffled around move order for other pokémon. It's just that in those cases, it's usually one move at most that have been cut (like Bellsprout and Weepinbell losing their last level-up slot) or have been moved to an earlier level-up slot (Spearow/Fearow learning Assurance where Pursuit used to be, and Take Down taking Assurance's old slot).
I think a lot of the strange issues with the BDSP learnsets would have been fixed if they had gotten reworked SWSH-style, since now a lot of the changes feel rather ham-fisted. I wonder if it was caused by a lack of time from either GF or ILCA, or if ILCA weren't allowed to make sweeping changes to learnsets (though they did give Probopass Body Press as a completely new addition, that wasn't a compensation for a removed move
).
Edit: Also, I don't think High Jump Kick would have been fitting as replacement for Doduo, Stantler etc. High Jump Kick is described in-game as a knee kick, rather than a dropkick like Jump Kick. However, Close Combat would have fit both Doduo and Stantler nicely imo.
I like that Lunge got some distribution outside Bug-types, but it doesn't make up for the lost Fighting-type coverage..
