So, it seems that you can get epic neck and ring as quest reward from Golden Lotus and Klaxxi when you hit exalted. I already bought valor necklace couple of weeks ago, and that GL neck seems to be better for me but no can do.
Tried to search what other factions offer at exalted and did not found anything yet. Anyone knows if August Celestials or Shado-Pan have similar quests at exalted where you can get shiny epicxxx? Tillers/Order Of The Ugly Serpent did not offer anything.
