I have seen the Warcraft logs Heroic statistics and seeing Subtlety so low made no sense to me. So I dig into those reports, encounter wise and saw 1-10 parses per Heroic kills as Subtlety.
They are VERY skewed right now. Dont be sad, my fellow Subs, we do better than that (I was pulling 190k average last night on Nythendra/Elerethe/Ilgynoth, and I expect to have 200k+ DPS this night on Ursoc).
