Yeah this season is skewed. Either way, its not about numbers. Go make a premade paladin on the PTR if you don't have a PVP geared Ret, any of you, and try to do high rated pvp. Do you know the last time I saw a Ret Paladin on the other team above 1700ish this season? Quite a while. And any other time we have seen one, its just train the paladin and he explodes. I'm not even sure how people can think specs like Ret (and others, yes, most notably Enhance) are in fine places. Just walk into an arena and quit dueling outside Shrine.
Edit: For clarification, I agree with you.
