Furthermore it'd barely help Ice because making an already rare offensive type even worse just means Grass-type moves get used even less and that Grass resistance becomes much less valuable.
What Ice should get is Flying and Ground resistance, these are currently two of the best offensive types and make for a currently nearly unresisted combination. This would make Ice types much more valuably defensively without nerfing Flying or Ground too much (as they are still excellent types both offensively and defensively).
