Since the nerf on the respawn times on the Stone guardians in Guo-Lai halls has anyone else noticed a steep drop in the droprates of the keys? Usually id get 2-3 just from the mobs i kill during dailies, and then 1 or 2 more farming the stone guardians. since the nerf I havent got a single key and ive been farming all kinds of different Mogu for significant amounts of time.
