I want to show my opinion not much about new events and new features, there are even too many about them, but about the currently implemented everyday game features.

Feel free to comment about them too.

***

1) Black Market.

The feature is fine as it is now in general, but should be added, imho, a wider quantity of ninjas whose fragments, time to time, appear there, available for with coupons and with coins, and imho should be added also the discount for medal users of every ingots/coupons cost there is.

2) Ninja exams.

The event is fine, but if has to be our main source of magatamas every day, then should be added a chance to get level 3-4-5s exactly like cave exploration does.

3) Ninja test.

This feature rewards should be wholly rethought to be extremely more appealing if we get 7-9/10 or 10/10, if bbqs, coins and basic refinement runes would be replaced by advance threads, optional refinement packs and ability scrolls, imho, the feature would not be anymore altogether skipped by the players.

4) Wanteds and treasure hunts.

The feature is fine, in general, but since is the only source of free tactics pages then, imho, the chance to drop them in treasure hunts should be higher and i would remove the chance to get coins. I would also add other rewards for the times a wanted do not drop treasure maps, so that people do not avoid doing them just because they grant exp, optional refinement packs, charm packs or myoboku grasps/gifts should be good options.

5) group, survival, arena and ranked shops

Those shops begins to feel way too much outdated, the ninja fragments they grant are not anymore competitive and in particular survival and ranked shops on a not even that very late game they feel like only a way to farm fragments for ninja refinement. A more frequent update of them would be indeed welcomed.

6) summon and space time shops.

Summon shop have the same kind of problem other shops have. Imho it should be updated with unbound rune packets (why are them in arena shop only?) and with the new summons fragments with very high costs, of course.

Space time shop instead, imho, has a serious issue of too high prices for the quantity of space time currency we actually get daily. The costs, imho, should be cut by 5-10 times and the ninja pull should be widened too.

7) Monthly Event.

This feature lacks general updateds since too many months and has been never updated, not even once since 3.0 onwards.

Why not adding there purification protection runes, advanced refinements, advanced threads and ability scrolls?

Obviously at a cost that is in accord with the other things there available (so for example, 20 points for purification protection runes up to 5 times per day, 45 points for advanced refinements up to 5 times per day, 60 for advanced threads up to twice per day and 105 for ability scrolls up to twice per day).

As is right now, for late f2p gamers, is just a source of 8 free seal scrolls per month and some ninja fragments while could be a way better source of material.

8) Survival Trial

this is the most recently updated every day feature, and, in fact, works pretty good. Nothing to say about this except that maybe the difference in rewards between the various difficulties should be wider and well set.

9) Cave exploration

The event is fine as is now, because, thankfully, the monthly rebate gave it a new life, i hope something like that could be made also for the other features.

10) Space time chips shop.

As many of the other shops, this feature lacks updates in terms of what we can sell there and also in what we can buy there. An increase of the number of options in both the sides would be pretty welcomed, indeed (for example by letting us sell cloths and medium refinements too, to not talk about super kage and naraka scrolls and by letting us buy charm pack fragments and why not, also exchange them for space time shop currency).

That's all, if i forgot something feel free to talk about it too.
