I was just thinking... Ice types have always found it hard to achieve a slot on competitive teams. This is because although a very decent offensive type, it is the worst defensive type: only resisting itself, and being weak to Rock, Fire, Steel and Fighting attacks. Three of which are very common attacking types. Therefore, Ice moves are seen often, but not on Ice Pokemon.
I use them, because I love them, and like STAB on my Ice attacks. But for most people who do use them, it is because Dragons dominate the battlefields. However, FAIRY types are arriving, who are set to be the perfect dragon counter, and potentially be immune or resist Dragon moves, something Ice can't do.
So, I foresee a great decline in the already sparse popularity of Ice types, and this saddens me.
I hope Gen VI brings some redeeming factor to Ice. Hail has always be an under appreciated weather condition. It's most similar in function to Sandstorm, which boosts Rock types' Special Defence by 50%; I would like to see a similar effect from Hail for Ice types. Maybe then, we might see Hail more, and so even see Blizzard being used, because I swear the only Ice attack being flung around is Ice Beam, because people prefer the accuracy. And it may make some people reconsider Ice types.
Without this, or extremely strong stats on Ice pokemon, or Ice resisting and being strong against Fairy or something, I think the only aspect of the Ice-type we will see, will be the occasional Ice Beam from a Water Pokemon, fending off Grass and Dragon advances.
Just a passing thought... let me know any opinions you have.
