If you are saying that any team should have a Steel-type or use Hail just to counter one Pokemon [Druddigon] then yes, it is broken. Metagames should not be that centralised, especially in the lower tiers. Teams in RU use quite a few NU or PU Pokemon, and I don't want to see that changing in favour of a more OU-like structure where a third of teams have a specific Pokemon. Druddigon's defensive stats are actually quite solid, and it is hard to find a 1HKO'er that is not resisted by Dragon. I rest my case.
