not everyone wants to use that you know i for example wont use it and for me it pretty much killed the whole competetive aspect since effort doesnt get rewarded at all anymore heck it even gets punished now
To be fair, it still requires you to train the Pokémon up to level 100 as well as have a Bottle Cap, neither of which are particularly easy to do in this game without lots of grinding or just straight up hacking. It's pretty much not worth bothering with unless you want to avoid having to soft reset for perfect legends/UBs. As someone who enjoys breeding for perfect Pokémon, I'm not a fan of it either, but I don't think it's accurate to say it doesn't reward effort.
Totally unrelated, but looking for spare Ice Stone, Moon Stone, and King's Rock. Can trade spitbacks of HA Mareanie, HA Alola-Sandshrew, HA Alola-Vulpix, Cubone, Wingull, Pichu, Porygon, and Meowth. PM me if interested.
