I don't really see the big issue here with these events. I recharged 10k ingots. Spent 2500 of those on seal scrolls and, with free points, bought another 10 scrolls. Didn't get Ay (of course) or the 500 coupon - but still got 2000 coupons free on top of it. That's not counting a bunch of summon scrolls/magatama.
I can understand why some would be mad at the timing - especially after several people already dumped hundreds into the naruto wheel. But it seems the arguments have drifted off from that.
Seriously guys, no one is going to get Ay - this is just free stuff. The timing is...questionable but there really isn't much room to complain here over some other events in the past.
