We have quite a few TM's these days, getting as high as 100 in the latest games. Some of these moves are terrible, but some are amazing. Generation 5 made it so TM's have infinite use, making them a lot better, and making our lives a lot easier. What changes would you like to see with TM's in generation 8? Which ones do you want gone? Which ones do you want added? Do you like spinach? How many TM's should there be? I think it would be fine to keep it at 100, but if we have more, that's totally fine. I think the TM for Hydro Pump would be pretty cool. It is fairly similar to Fire Blast, Thunder, Blizzard, etc., and I think it would be fun to give it to otherwise weak water Pokémon that don't have access yet.
I'd like to see TMs for new moves that more than one Pokémon can learn. It'd be nice to vary up the playing field for the Pokémon that already exist. And yes, I like spinach.
A lot of the moves that used to be TMs in older gens were turned into Tutor Moves come Gen 7. I can't complain TOO much because of that, since they're still obtainable, but I'd like to see Giga Drain and Hone Claws come back in TM form
I really want another Fairy type TM. I think Draining Kiss or Moonblast could make for good TMs so that more mons can get a reliable recovery move, or simply a better Fairy move than Dazzling Gleam. I think we should get rid of Quash and Brutal Swing as a TM because I don’t think anyone uses them. And I also like spinach.
