>>40096575As much as I love water, water needs to be weak to poison to keep them in check and to make poison more relevant as an attacking type, which would indirectly nerf fairies too.
Giving ice another type to be super-effective against isn't the best of ideas, though, since ice is already one of THE best attacking types, while roughly NONE the most common ice move users in the top metagames are actual ice-types. If anything, buff Freeze-Dry's power since that move is actually still learned only by ice-types.
Ice resisting water is perfect, though. Defensive ice-types desperately need a buff and water and ice mutually resisting each other makes sense to me
