>>50941063Nah, a lot of water types do get Ice coverage but you're overestimating how often it's actually used. Literally none of the Water types in OU or UU commonly run Ice moves (except Icy Wind Keldeo but that's 55 BP). Dual STABs + utility moves like Recover, Flip Turn, Hazards, Defog, or Toxic are usually just better.
Grass still manages to be an incredibly useful counter to Water and on top of that has a bunch of other good defensive utility as a Ground and Electric resist as well as Powder/Leech immunity. Yes, it has a lot of weaknesses but unlike e.g. Rock its resists are actually useful and valuable which lets it still be a great defensive type. Even better
