Is there any way that policy in terms of the Identity of National Dex can change in the future? One of the aspects of National Dex that's always put me off personally is the way that Near-Universal TM's are not learnable by any future Pokemon. While this mainly talks about Hidden Power being unlearnable by Gen 8 and 9 Pokemon, there's also Toxic which is considered a near-universal TM before Gen 8.
The concept of near-universal TM's has always been around since gen 1, with specific Pokemon marked as exceptions, being unable to learn TM's in general. TM-less Pokemon continue to be a thing into Gen 8 and 9, with Blipbug and Applin being specifically designed to not aquire these otherwise universal TM's.
Generally my question is would a Policy Review thread for something like this be on the table? Since the metagame revolves around bringing Pokemon from after Gen 7 into the game, this would imply that they'd be able to learn these universal TM's as well unless they're designated as Pokemon that cannot learn TM's.
Near Universal Moves in gen 7 that have the status revoked in further generations are the following:
- Confide
- Double Team
- Frustration
- Hidden Power
- Return
- Swagger
- Toxic
Unless there is a significant push from natdex formats playerbases, a pr thread is very unlikely to happen, especially since universal tms are not a topic brought up often at all in the first place and thus doesn't seem to be generally a concern.
I personally believe National Dex should stick to moves Pokemon or their pre-evolutions actually got, and not arbitrarily give moves that were actually never given to the mons in question, especially since gamefreak sometimes do kind of whatever it wants regarding those moves -
they don't even share the same distribution in the first place! Some moves you listed are great examples of that (all these pokemon existed in gen7):
-Magearna does not learn Toxic.
-Pyukumuku has access to some moves through TMs, most notably Rest, but never learnt any of Frustration, Hidden Power or Return.
-Burmy learns Hidden Power, but neither of Frustration or Return.
-Drampa, Guzzlord, Naganadel, Stakataka and Zeraora do not learn Swagger, despite being Pokemon that can learn TMs. Guzzlord and Stakataka also do not learn Confide.
-Tapu Bulu and Stakataka do not learn Double Team.
On an adjacent topic, Tera Blast is also a super odd case introduced in gen9. It is a tm accessible even to the Pokemon that were known to be TM-less (like applin), except Cosmoem, Cosmog, Magikarp, Ditto, and Terapagos - the turtle in particular not even being a TM-less pokemon.
More generally, National Dex should minimize arbitrary decisions as much as possible in my opinion, and even though expanding universal TMs could makes sense on paper, we ultimately cannot know for sure if these moves would have gotten the distribution we would have expected them to have.
