The Egg Groups have made some abnormalities for Pokémon breeding, and some Pokémon who deserves secondary Egg Groups only get single Egg Group, when others who are dual-Group gets put in wrong groups. However, the system hasn't gotten any revamps, even when Fairy-typing was introduced to balance Type Advantage charts. And this will not get any future revamps forever. Until the official further notice. Most notably, Field Egg Group has so many mismatched Pokémon that should have been in another group that fits them better, but that's one of the abnormalities. And yes, some unique Egg Group combinations have gotten wasted and so far no Pokémon belong to those. But for now, big question! If the Egg Group system will get any change, reboot or reset, which Pokémon you think should got their Egg Groups altered? (No Legendary, Mythical or UB Pokémon, please.) My thoughts (and examples, maybe): Spoiler Ralts line should be in Fairy egg group in addition to Amorphous egg group due to the addition of Fairy-type. Eevee-line should deserve unique Field/Amorphous egg group due tk unstable genetic makeups that most mammal Pokémon don't have. Gastly line should be in Amorphous/Mineral egg group due to being based on pollution gases. Shedinja should be in Undiscovered egg group.
