Season of Discovery
Removed gear from player-characters who obtained it from an unintentionally available testing NPC.
The new relics that are crafted from Ahn'Qiraj are no longer Unique.
Players dying outside the entrance to the areas of the Gates of Ahn'Qiraj, The Scarab Dais, or The Scarab Wall will no longer use the same graveyard as those who die inside Ruins or Temple of Ahn'Qiraj raids.

Divine Light will now correctly activate Scarab Brooch.
"Fixed a problem with the Hunter 4-piece Tier 12 set bonus where its effect was not being properly consumed by some Shots."
the problem was that while the proc was up, serpent sting and black arrow did not cost focus but did not consume the proc.
Additionally, if lock and load was up while the proc was up as well, you could spam arcane shot without any focus cost at all.
I reported this about 4 weeks ago.
The fix made it that now the 4set proc does not affect serpent sting and black arrow at all... so if you don't have enough focus for those shots when the 4set proc, you can't use them.
and additionally, if lock and load is up while the 4set is working, the proc will be consumed by the explosive shot. meaning, you will "waste" the 4set proc.
not much of a fix, more of a broken differently now.
