Would it be possible to remove Rock's weakness to Ground to help make it a bit better defensively? I mean the two have always been linked since Generation I, and while I get brittle rock being shattered by an Earthquake I think it would make some sense if Rock wasn't weak to Ground anymore since they're both the "earth".

I've seen people say Rock would be too good without that EQ weakness, but I think if Game Freak did this then they could give Grass and Steel some more offensive options to counter this.
