Am I missing anything or was the passive bonus of tailoring not updated? (Northern Cloth Scavenging)
They didn't change the name, but it works on cata cloth. Although I'm not sure why you'd need it for Panda cloth... Stacks of it are already under 20g on my server.
Apparently there were enough complaints from enchanters about being forced to share their disenchanting ability that they decided to give everyone the cloth gathering bonus, too.
It's working... I've been getting the extra cloth on my mage... after everyone loots I wait by the mobs and then they twinkle again.... I grab my cloth then. ( or lose it to another tailor )
