Found one more bug, which,in this case, resets epic world boss WQ!
So what I have been doing past couple of days is:
Go to the world boss quest (DANGER: Flotsam) and kill it (completing quest) ;Queue for LFR, enter it and kill atleast one boss ;Leave instance and relog ;Hearthstone to dalaran and enter demon hunter class hall ;Go back to dalaran, relaunch the game ;It pops up again.I didn't get any gear drops. I believe it only has a chance to drop gear the first time you kill him.However I did the world quest twice a day everyday since wednesday, pretty much stacked with order resources ^^
Forgot to mention that I did not swap servers to find group for Flotsam, just wait for enough people to gather on your realm and then kill it.
