>>50818237This is such a bad argument.
Pokémon are not or bad just because of their type. They are several factors that determine that, BST, Stat Distro, Movepool and its ability. A Pokémon is good because at least 2 or more of those are good. Of course the more of those attributes you excel at the better. You can be good despite having an awful typing.
Ice Type is TERRIBLE on the defense and GF's mold for ice-types is "Glacier" aka Slow and Bulky. Which is an awful fit for a Type with so many weaknesses and no resistances. Of course, not all Ice types are defensive and what do you know, the most successful ones ARE the ones built for agro.
Ice is a “Glass Canon” type, so the Pokémon who do that work better for it.
