Within the past couple hours blizzard nerfed Netherweave cloth drops and green drops from all BC raids and dungeons. An insane nerf it may be worth it to stockpile some because an entire Tempest keep run got me 0 cloth and greens down from several stacks and 10+ greens.
Seems like a temp fix to stop botters but will be messing with the AH, just wanted to warn people.
