It's impossible to make ICE op with realistic buffs. Stealth Rocks. also, Every Pokemon and their niece have access to at least one super effective move to keep them in check.
But to buff them enough so that Dragons aren't a "problem" anymore? (which I don't really even think they are in the first place, but whatever) Like I said, it may end up introducing some unnecessary power creep, depending on how they decide to handle it.
I mean, to take a type that's already bad and make it into something that effectively handles one of the most powerful types (which often carry moves that destroy Ice types as it is), that would require some pretty extreme buffing.
