hey guys i just killed over 40 rares in Isle of Thunder and still haven't seen a single key. I read in many forums that you can get more than one key per weekend as long as they are not from the same source eg. 1 from chest, 1 from rare, and even from daily quests (arcane trove) if you are lucky. However it just doesn't work for me. I got one key on wednesday from some chest that spawns around the island, finished scenario and been farming rares since then. Any idea if the maybe hotfixed it?
