Well I'd been seeing some talk on the official forums about the latest PTR patch adding Primal Nethers to the epic helm recipes. At first I was in denial - I did not want to think about it. Then after seeing it again in a different thread I decided to take a deep breath and log into the PTR to check my recipe. Sure enough... it now requires a Primal Nether.
Kayree is terribly saddened and devastated by this. She was so looking forward to being the only level 60 tank walking around in epic Gizmatic Goggles. Obviously Blizz wants to make sure that only level 70 players can craft this item, hence the "nerf". I realize it's not technically a nerf, since they merely added a new ingredient to the recipe. But since that ingredient is BoP and can only be acquired by players capable of surviving Heroic instances, it may as well be a nerf to this wee gnome. I guess she will just have to enjoy her PTR copy, as that's the only way she's going to be using it. At least they didn't take that one away from me... <sniff>
