Nice spot Del. I'd actually stopped checking Kripp's page as he hadn't posted anything decent for ages
As for the message in the video, indeed Kripp states haste > crit.
He goes a little further tho: Mastery > Haste > Crit (this is not really new information, read on....)
You probably picked this up, but there's a subtle difference between what he says here and what I've read elsewhere. He says COMPLETELY max out your mastery. Since he says haste > crit, I assume he means completely reforge crit into mastery. I've noticed the Wild Quiver proc is providing a massive amount of PASSIVE extra damage though. Tentavively, I'd say around 10-15% of total damage and Chewwie's mastery is low, tbh.
Kripparrian is mustard and appears to have really done his homework, so I'll play around with his advice. One thing that makes me sceptical of the APPLICATION of his advice to ALL hunters: he plays in full BiS gear. No-one in PCG does. We'll have to drop below 50% crit to do what he's saying. Without the aid of a SIM, I'm unsure of the effect of the different stats weightings at different levels. I'll give it a go though, for sure. Cheers for posting that Del!
