>>47186801Revamp sun mechanics and make it so either fire attacks don't deal ×3 damage to grass types in the sun or boost the power of grass type moves in the sun. Gamefreak didn't balance sun and rain mechanics. For rain, almost all of the rain based abilities are given to water-types, which also gain the additional effect of increasing their STAB. Sun is weird in that it boosts a weakness to grass types, despite grass types holding a majority of the sun-baked abilities. It likely ended up this way due to weather existing before abilities, but nothing was ever done to balance them out.
