I don't mind Mega-Sableye, because they can introduce variety and new obstacles. It's kinda interesting when Megas exist but the originals can also be used, maybe more effectively, then using them is a choice aand the originals aren't completely defunct.. But yeah they add many Megas to popular Pokémon when their original forms were already used often. They could try Mega changes of others, like Lanturn. They also have Alolan forms, will those carry on? That might limit some Pokémon from getting Megas.
