steel should be called metal

grass should be called plant

"ground" shouldn't be a type

flying should've been included when they split dragon off into its own type in the card game, the symbol should've been a wing and the type would be called flying, not dragon

why do bugs get their own type but there's no fish type or reptile type or primate type or whatever, either have no separate bug type or create more animal types (i would prefer the former)

there shouldn't be pokemon that are half-normal type, hurr durr this organism is only a little bit poisonous, let's call it half poison half normal. this bird can only fly a little bit, it can only use one wing, it's half normal half flying

metal (aka "steel") should be weak to electric

they should've came up with a different name for fairy

there should be a pokemon with every type combination, it's more than 20 years later and there's still no "fire and ice" pokemon, or fighting/electric or fire/grass or dark/electric
