I feel each event should have event points so we can just unlock the stuff we want instead of unlocking them in a linear order. I missed the first week so I am guessing I will miss out on the last ten items for however long till when or if they do this event again. But honestly all I really want in the possible 30 items is the Yoroi armor set, sol devil AR skin, and Yokai helmet. Also the xp boost and challenge swaps.
