>>36419770I have a suspicion they make water types so common so the grass starters not-suck.
The thing is that I don't think they planned it. In gen I and II it wasn't an issue but as the Bug, Ice, Poison, Flying types developed (such as move X-scissor) they nerfed little by little. The sad thing is that most of the weaknesses make sense.
The least they could do is make grass resistant to Fairy instead of fire.
