I would advice against this since it stacks with Chansey’s Eviolite boost and makes it too universal and affects early game too easily, as it can become annoying to face against a Patrat or Munchlax that somehow take little damage our starter’s STAB.
Remember not get into wishlisting territory here so I’m not gonna suggest anything.
Here’s another unpopular opinion from yours truly; the power creep is nowhere as bad as people made it out to be and is just a result of Game Freak being careless about balacing in the long run despite good intentions. Also, BST only mattered if it gets too low (which nowadays rarely happens, but it still happens), and stat distribution is more important in the long run.
- It only becomes nadir in Generation 5, with numerous great in-game Pokémon introduced, strong Legendary Pokémon that became stables like Landorus, perma-weather wars, the Type Gems with their 1.5x power boost (you can use multiple vs only one Z-Crystal per team), the Hidden Ability as a concept, etc.
- Generation 6 have issues with Mega Evolution, which reached fever peak in ORAS mostly thanks to the Mega Evolution form for Salamence, Metagross and Rayquaza (moreso due to execution than concept themselves), and Primal Groudon is a true beast of it’s own as well. That said, while Yveltal, Xerneas, Talonflame, Greninja and a multitude of Mega Evolution are nothing to scoff at, many Gen 6 Pokémon ends up being overlooked.
- Generation 7 brought us the Tapus - which resulted nerf of damage boost (from 1.5x to 1.3x) for Electric, Psychic and Grassy Terrains - and introduced Ultra Beasts, a few of which are competititve staples. Z-Moves are more reasonable to deal with compared to Type Gems, but with Mega Evolution and Primal Reversion involved, things aren’t that smooth. Aside of a few, though, many of Gen 7 Pokémon got overlooked quickly, less so in-game than in competitive, such as the controversial decision to make too many of them unreasonably slow.
- Generation 8, despite the problems Dynamax brought in both Smogon and VGC, is an even bigger mixed bags. While it introduced more winners, with some working too well like Dracovish, Cinderace and Galarian Darmanitan, it also introduced more “losers” (almost unviable to outright unviable) to say the least. While Eternatus is a fan favorite in competitive due to simply being really good all-around, Zacian and Calyrex are despised for being way too overspecialized. This have more to do with troubled development and an especially bad strict time constraint given to the new development team. Yikes. BDSP is more akin to Gen 4 but with modern movesets, so nothing too worrisome to think off.
We don’t know how Generation 9 will fares, and we can only know how Terastal would performs in execution and if it is ban-worthy or not, but power creep, at the moment, should be the least of our worries compared to, say, an increasing amount of dumb overspecializations or stagnant ideas.
