Is there a particular reason Squenix isn't tweaking the old level 50 beast tribe exp? It's not even worth the 20 minutes it takes to complete them for 48k exp (at level 48) vs. a dungeon where the last boss is giving 100k xp (at level 48).
Both take the same amount of time to complete as the Heavenward ones, but for some reason, going back to long outdated expired content, gives you an insignificant amount of exp, for what? Vanity objects. Is that really a good enough reason to not just simply buff the exp rewards?
