While i was checking new things in PTR i stumbled upon this guy: "Master Nguyen", he is titled as one of the "five sorcerers", i found him in the house at the top of the rock spire that is linked to the temple of the jade serpent, he had this buff: The Power of the Storm.
the weird thing is that when i went back again to check him "just after 20 mins or so"....... *boof* he disappeared!!!! so what you guys think of the role that these 5 sorcerers will play in this patch, and what is their link to lei-shen the "Thunder King".
