>>53857263Nothing like a few simple fixes can't hurt, ignore the stats boost and ability change, I don't think GF ever drastically boosted a mons stats or changed their ability, but they can introduce a special item for Tinkaton or make her Gigaton Hammer work like Freeze-Dry making it super-effective against Steel types(why they didn't do that in the first place, I have no idea?), and some strong effective against Steel type moves like Fire/Ground(Earthquake)/Fight and some Electric moves and Smack Down specifically for Corviknight.
I think what kind of hindered Tinkaton is before her the last Fairy/Steel was Zacian(The Dog of Unspeakable Brokenness) and how badly that mon is known to destroy any Pokemon game it gets added into Single-Handly(Just look what it's doing to Pokemon Unite), so GF took precautions and put the entirely of Tinkaton's power into her Signature Move, but then they did an 180 and made OP mons anyways, so it was all for naught...
Also, their balance, lore team, and design team barely interact with each other, so it's most likely miscommunication is what happened.
I'm going to be honest here, when GF decides to remove Terra from the game, a lot of the Paldean mons are going to be in need of buffs since they pretty much pigeonholed them into relying on Terras, it's going to be Megas all over again.
