um i don't understand last great plates i got 78 kushina frags and this one has also been eventful, i don't think they "nerfed" it as many people in my server are getting a plethora of seal scrolls etc, the rewards are consistently good within the event even if you don't get frags because 10 coupons for a medium refine or bond scroll is decent and the 50k coins is the only reward on it which may not be worth it but it's not like you get that from every 10 spins
