Ok so I have talked to numerous Tank friends and people on the server that I know and none of them are experiencing what I am. For some strange reason I logged on today and for no reason I have 40,000 more health than I did last night. Im more Mastery gemmed than Stamina and had around 214,000 HP yesterday. Now I have 254,000 HP today unbuffed with 1 Stamina trinket on. I cannot explain why but im not gonna complain....at least about that. So we were finishing up the rest of our Heroic Dragon Soul lockout tonight killing Spine and Madness and now I cannot generate ANY threat....I mean any. This has nothing to do with the class changes. We raided on Tuesday after the patch and my threat was completely fine. Now im doing as much threat as a normal melee class. I tried logging in and out, switching presences multiple times and resetting my talents/spec. Nothing worked. We finished the raid night but I had to constantly taunt on CD and melee took some hits. So I have mysterious health and no threat now. Wtf.....??? Anyone else have this issue?
