>>37166626The original concept of ice is that it's an all-out-offense type that does good damage against a lot of big threats, but can't take many hits itself.
The problem with this is that being ice type and knowing ice type moves are two separate things, and there's no point in bothering with ice types if a lot of non-ice pokemon can learn the moves like Ice Beam instead. So the main way to fix Ice offensively would be to remove everyone else's ability to learn the good ice attacks.
As for defense, Ice is really up shit's creek. Maybe give it resistances to ground and fairy or something like that. Really Regice in Gen 3 was the last time an ice mon could work defensively, and the physical/special split totally changed that too.
Other things? Maybe buff hail to make it more viable. Sandstorm teams could work because there's a plethora of pokemon that benefit from sandstorm, but with Hail it's JUST ice types alone. Maybe give ice types a really big defensive boost in hail or something and also make a few other types like water immune to the damage? And maybe give us an ice-type stealth rock that is ONLY learned by a select few ice pokemon, to bolster their viability.
