I wonder when they will learn the lesson that every time the introduce a ninja available with coupons only they should add, together with it, also or a permanent f2p feature or 1/2 new skillbreaktrough to balance the fact p2w get something and f2p nothing.

The main issue of this version of the fukurokumaru deal is the value they give to power up items. There are a bunch like for example advanced threads and treasure tool essences that are way overpriced every time they appear in redeemable events so they put them there thinking they have th value they give them when is not right. If the step with advanced threads had actually 100 of them then, maybe, would be appealing, but 6 of them are not even worth 1 wish credit and does not matter if they value them 69 coupons each one, they are not worth more than 15-20 coupons for what they actually grant in power terms. The same is for treasure tool essences. If in average we get 11 purple essences by spending 4000 coupons in the ability treasure (two 3x as the draw by 10 rewards + 5 redeemed in the shop) you cannot put one gold essence like if was worth 10k coupons when is just worth 6k or a purple essence like if was worth 1000 coupons when is just worth 400.
