I like the current legendary system offered but I feel like all the caves and legendary special locations in these games are empty and redundant without their respective legendary mons. Additionally i feel like a whole aspect of the core game series is missing with all the legendaries missing. Maybe instead al legendaries are incorporated into the game and can be found in their regular location, but instead of triggering a battling sequence you just hear their cry and register them in the Pokédex. These legendaries can spawn in at certain times and can disappear after encountering them. But this way all legendaries are incorporated without having them interfere with pvp and no one can catch them. But these locations/caves still get explored and you have a reason to find them (registering them).
