To make this event appealing they should remove everything that's less worth than 50 coupons or that is worth it but none would ever spend coupons to get them, or they should add other steps before the 50 goal (for 5, 10, 25 for example) or they should cut the cost for 1 roll to 20/25 coupons and add 1 free roll per day. (The great plates event was WAY better than this event, but was removed and never showed again just because people didn't like it).

investing 50 coupons or 498 for 10 tries (meh...) is not a little thing for a f2p or for a low cashing player, to do it on a board where out of 14 slots 2 of them are less worth than 50 coupons (2 seal scroll fragments, 20 coupons), other 3 are worth it but wholly out of any purchasing intention any not out of mind person could have (stamina potion, summon scroll, 3 purification protection runes) and other 4 are subpar or very not useful after the first 2-3 times you get them in your whole playing life time (tendo fragment, summon contract scroll for the not useful part and 5 unbound runes packet and 5 cave keys for the subpar part) doesn't seem that appealing.

The fact that are there 100 coupons, 1 charm pack, 1 magatama level 5 pack, 30 kushina fragments and 80 minato fragments as the other 5 slots doesn't induce them in any way in trying more than once per event to see if they are lucky (overall knowing or reasonable thinking that all of the good rewards have not at all an 1/14 chance to be rolled out).

The only good thing i see in this sna(tch) is that they finally put it not together with lucky board, but still not worth more than 1 try per week imho.
