Furthermore, don't say that we also have few ghost or dragon types, they aren't like fire type. Fire is part of the grass/fire/water triangle, and the ammount of fire type Pokemons is much lower than grass and water.
I really don't know if GF has some trouble on creating fire type Pokemons, the fact is that we have few of them. Plus, Magmortar is the only fire type with a thee-stage evolutionary line that isn't a starter. This reflects how is hard to create a complete line of fire type Pokemons.
