Quests in this game are not like that. The numbers are small and the circles are not in difficult locations. Do all the circles, return to hub, lots of xps for turn ins. That's why mine are gone, I was like, EASY STUFF when i was leveling my first character.
I tried to fate grind last night, sitting around at the Aetheryte and racing people to get to each fate circle in time is not fun to me. I'd rather spam battleleves to be honest.
