While completing 100% of the quests can certainly be its own reward, it might be handy to bump some of them (maybe the 1hp quests) to reward an epic chest. OR, mayhap completing 100% could unlock a special figure?
1 loot fairy gives better loot than 1 quest atm. And getting 1 fairy's loot is a lot easier and faster.
