I have had this quest for awhile and every so often I will pop into forrest ruins and mass kill elementals when they are not being hunted (usually the un-camped higher level ones).
Anyways I have gotten everything for this quest but the elemental core essence I believe (one of the quest updates). I know I have killed 300+ elementals in this quest, heck maybe more. Is this quest broken or does it just take a excessive amount of elementals to complete? I have done 4 other mastery quests and they didn't take anywhere near this amount of time to complete. I did a /petition asking if it was bugged and I got a really helpful gm *sarcasim*.
He tells me to follow the quest normally, seek help from other players, do a /bug on it lol. So I don't know what the deal.
