My warlock is affliction and her loot specialization is specifically set to affliction, not "current spec." Each and every single WQ without fail that provides a relic for her weapon, gives a fel or fire relic (which are strictly for the demonology and destruction weapons); never a shadow or blood relic.
My Paladin is protection spec and absolutely NEVER gets a WQ offering a holy relic; only iron. Trinkets offered from WQ never fail to provide +intellect (which is strictly for healer paladins).
Is this common with everyone else, that WQ's don't respect your chosen loot specialization?
