You know what would be the best way to get folks to do more fates but without tying it to some arbitrary grind? Tomes. Tack on being level capped rewards you with tomes now. It can be as low as 20/10 (uncapped/capped) and you damn well will see more people doing them. Tying fates to bad seasonal events (youkai) or relic are short lived and annoying. But being able to grind out lore via fates would have helped out with the monotony of ARF.
