I found 20x quest xp fun and redid quests I hadn't done in years. The large xp rewards gave me the satisfaction that other games deliver with awesome loot, a cool title or a visible change to the game world/events. Currently, SotA has few/none of those things so, for me, the large xp reward as loot was an enjoyable substitute. Now that it's gone, quest rewards are back to an unsatisfying norm. I still enjoy doing other things in SotA, but really enjoyed the extra xp and hope it returns in some form or another.
