Ice really is an odd beast.

It has way too many weaknesses to the most common types. And ironically doesn't have enough types it's strong against to compensate.

The weaknesses it does have are such that it's basically impossible for a secondary type to make it any better

A ton of its pokemon are slow as shit, or defensively oriented, which is the opposite of what a type with so many weaknesses needs. Even worse, the "defensive" ice types really aren't all that bulky.

A ton of its pokemon are physically oriented, despite being a Special type in gens 1-3, and despite its best moves being Special Attacks.

The whole type is a mess. It's telling that they had to completely redo the ice-type weather condition to make the type a tiny bit more bulky. A weather benefit they have never had to do for any other type.
