The fact that they were Guardian Deities should've tipped you off from the get-go that they were legendaries.They just seemed to me like they could have been like the Lucario / Zoroarks of the gen, normal pokemon with bigger roles. I was more of a personal wish anyways as I wanted a competivlly viable Tapu Koko. I don't do soft resetting.
Cosmog wastes dex space as it learns no attacking moves, evolves into another pokemon that can't attack, then evolves into the version mascot only to be unbreedable and therefore unobtainable. I get it may be important to the plot but an alt form would have worked better. Left dex space for a real Dolphin.
As for Cosmog... It's not like making it an alt form would change much. They'd still be putting time and resources into making it, so we wouldn't have gotten a dolphin or something else in its place regardless.
