+1 for actually telling us events a full day beforehand. Would still prefer a little more time in advance though, especially considering half the events we get now seem to only last a few days. Help the players budget better and you'll see more income in the long run.
Moving on...Events this week are average, at best. Nothing amazing, nothing terrible. My biggest complaints align with what others are already saying. Why is, arguably, the best event in the rotation only up for 3 days? If so the keys better be 5 coupons at the most otherwise it's just another rip off. We can earn 60 keys in those 3 days, the first reward (3 seals) totals a value of 375x. At 10x per key we would literally spend almost twice that value just to get to that first reward, and knowing the chance of getting those packs on that board no way would we make up the value difference. Also at 10x per key this would be the most expensive Hidan yet.
Truthfully, I gladly paid for the release of him on Lucky Board because the value there was all around amazing. Not only was he cheaper than he is now but I also got the bonuses from all those rolls. Now tell me why the hell a player would take these crap rolls over something that like and still spend more to get the same thing months later? Now this is all speculated off the idea that keys will be 10x per key but if you simply cut that in half, or already have and we just don't know, then all is fair and well.
Outside of that other events are all average but acceptable:
Bond system is a new permanent feature with freebies. Always good. Thanks for pushing that out.
Rebates are always fine, seal/summon/key/BA/spending etc, they will always be accepted because of the nature of the system.
Puzzles are annoying but hey, totally free.
Gift packs are similar to rebates. You do get a slight discount and a chance for decent extra reward so why not?
Time Limited Recruitment...This one is dicey. The event itself isn't too bad because nobody expects to get a full ninja or anything amazing flat out. It's just known as a decent way to get some threads/refines or fragments. That being said its value is based entirely off the rewards. With small changes it could be improved tremendously and made into a really great event. Just make sure the consumables are actually relevant (no low level refines, coins, food or dango TY) and add in or two ninja alongside the newer ones. Choose ones that are a bit older but still harder to get (Choza, B.S Kakashi or pains, other than Chiku*to) at a slightly lower cost. Helps out everyone as free players can farm or finish them with frags from who knows how long ago and others can push them to 4/5* if they choose.
