I thought about how to make ice and hail viable. I ain't no icefag, but it's a shame having so many cool mons impossible to use because ice sucks so hard. So here are my ideas:

>New resistances
Pretty obvious. Without giving an insane buff, my choices would be water and fairy. Water because it's such an overpowered type that giving a resistance to it to a lesser type might halp this one (like poison with fairy).
About fairy, I always thought that representing ice the thermical opposite of fire, it should too be resistant to fairies.
So now Ice resists itself, water and fairy, three very popular offensive types.

>Losing the rock weaknesses
Yeah, sounds like a retarded buff, but I thought about it. Even with the aforementioned buffs, ice would still suck too hard. The only way to actually improve it is losing the rock weakness, making it neutral.
