As a singles player myself, this seems a bit harsh on the balancing. Given they tend to balance the game around Doubles as the format they're trying to make an eSport out of, the Generation has had some banworthy mons, but I also think Singles has gained a decent number of influential-but-not-stupid Pokemon like Skeledirge and Meowscarada, Roaring Moon, Iron Valiant, and of course Great Tusk.The Sun + Moon anime series does have a Mimikyu who’s rotten-to-the-core that resent the Pikachu species’ popularity, which is noted as a large contrast to other members of it’s species. GF should not make the species feeling one-note in terms of potential personality between each species, otherwise it makes them too rigid for fanmade contents by making fans complacent about the species so-called behaviors.
Meanwhile, I’m having mixed feelings about this generation’s power creep.
One one hand, GF really took one step forward, two step backward considering an attempt of rebalancing Zacian (Zamazenta’s nerf isn’t so bad since it did get Body Press + wouldn’t care about Intimidate as much as the sword counterpart would), making sure Terastalization isn’t overwhelming like Dynamax and succeeded for the most part, and making Protean a lot less oppressive, but then we have even more overpowered moves and Pokémon within a single generation, to the point where plenty of Paldea-introduced non-Legendary Pokémon got either quickbanned or suspect banned within few months after Scarlet + Violet release, making their balancing act not sincere at all.
But on the other hand, barring a few stinkers, they did succeeded at making many of the newcomers useful for in-game and competitive, so it’s nice to see many new faces in Singles OU and Doubles OU, as well as VGC. It helps that most signature move and / or Ability were actually useful and gel well with the Pokémon’s toolkit, even it ended up working too well in a few cases.
Truth is, the power creep in earlier generations aren’t that bad, and it were the Pseudo-Legends, Legendary, Mythical and other restricted Pokémon to put the blame for it, since those from later generations were oftentimes blatantly better than what came before. While Gen 5 and, when considering Mega Evolution, Gen 6, were arguable exceptions, it wasn’t until Generation 9 that things went into an overdrive. Though Gen 8 can be considered as a harbringer.
Of the Tiering Actions that have happened so far, several of them are Pokemon that definitely are only busted in a 6v6 Singles context (Last Resorts having more faints for power, Chien-Pao and Chi-Yu, Cyclizar for Shed Tail spam, for example), Terastalization got looked at but so far is considered balanced, and Espathra legitimately feels like an accident in that regard as a one-mon Baton Pass chain. Flutter Mane and Iron Bundle seem like the only ones that stick out so far as massive misteps since they seem to have VGC viability on top of Min-Maxed Singles play.
I wouldn't call the effort perfect but I can't call the balancing act insincere just based on this, every Gen's had some stand out players, especially if we include the "big" players like Pseudos or Megas (Garchomp in Gen 4, a lot of Weather Abusers in Gen 5, several Gen 6 Megas, UB's like Pheromosa and Naganadel in Gen 7, etc)
