Doesn't know how to attack
This is so true and something to be very thankful for if you get this game. More Fire types, like everyone mentions because of Flint, and getting Ice Types before Route 217 are massive improvements, but it bothers me so much that they seem to be only giving the unrestricted dex for the player. (Judging by the Ice Gym's Snover.) Platinum also unrestricted other trainers. Flint's Team, the Ice Gym's Medicham, and the Electric Gym only having 2 out of 4 Pokemon being Electric Types is something they should've fixed. I don't care if it's faithful because it's being faithful to the problems if Flint still has two Fire types. (I will never stop beating this dead horse after they brought it back for the remake without fixing it!)DP's achilles heel was and forever will be the wretched Pokemon selection due to the restricted dex. Platinum solved that, and BDSP solved it even harder by going "fuck it, have a buncha shit not even in the Platinum dex via Underground". By those tokens, both of these games are immediately 500x better.
You could say SwSh's Dragon Gym Leader didn't have all Dragons, but he's also based around weather and his non-Dragons are at least reptiles (Sandaconda and Torkoal) or rugged enough to not stand out among Dragons... Wait, does Gigalith learn any Dragon Moves? *checks* Huh, and neither does Torkoal. Well, that weakens my argument but at least that wasn't from a restricted dex. Diamond and Pearl didn't even try for Pokemon that matched the trainer's theme and slapped on anything that could learn any move of the user's type, like Lopunny's Egg Move Fire Punch or even just Drifblim's Will-O-Wisp. Even back when I didn't realize Flint only had 2 Fire types because there were only 2 Fire types, I thought Will-O-Wisp was a stretch. (Yes, I'm complaining about Status Moves and yes, I get the irony of me doing that.)
Judging by the Ice Gym's Snover, they didn't fix this. Oh, and the Switch caring case with Cynthia's Platinum team is just fuel for the salty fire. Now that I'm sure they didn't do the one fix that would make me buy this game, I'm happy to watch the world burn. I'm sure most players can burn the world better than Flint.
