All shots have a 5 yard firing range and Kill Shot was just brought in line with that. It isn't a nerf, it's a fix.

And why is the article claiming stealth nerfs when it isn't anything of that sort? If anything, this patch has been great for hunters, especially PvE hunters of which I'm one so I'm glad that this patch went live. Blizzard acknowledged that the T9-2pc bonus was a bad design choice so even though the patch went live with it still being borked, they hotfixed it pretty damn quickly so the Serpent Sting crits now have a physical crit modifier. It's still a bit wonky with the meta-gem though, but it's way better than before and a step in the right direction.

What is funny though is that Volley was nerfed because Blizzard thought Hunters did too much AoE on Naxxramas trash. And now the co-efficient has been buffed back to the pre-nerf value because Hunters did shit AoE on Anub'arak's adds in 25m ToGC. Kinda reinforces the fact that balancing classes based on their trash DPS performance is never a good thing.

All in all, I'm happy with this patch, especially since I'm not a PvP hunter.
