Are we sure that bosses still parry haste? I've been seeing rumor-ish posts here and on Tankspot that it may be gone, on most or all bosses, and I'm having difficulty actually finding examples of parryhaste in Naxx WWSes. Instead, I'm seeing swings consistently falling within the margin of latency, whereas the parryhaste was clear on previous bosses, particularly some of Kara's.
A Faerlina example, from
this Disbanded WWS:
