The weekly emissary quest from Therazal gives a ridiculously low amount of flightstones (8) for what it is. To do this quest, you have to do a myriad of other quests and objectives, which of course may provide some flightstones. That being said, when it’s all said and done there’s no pay-off or excitement for completing this quest and you can only do it once a week.
Weekly quests should provide a larger sum of flightstones and would motivate more people to do it. For now, I don’t even want to pick it up anymore.
