They won't increase level cap for a while since players leveling doesn't put money in their pockets. ;P aside from that, apart from the puzzle, another eventless week for us F2P :D super happy about the arena though!

People saying the Mods aren't to blame, it's the Devs...

The fact is, they're BOTH to blame for different scenarios. The Mods are basically the communities voice, their role is to gather information from the community about the current events and the communities opinions of them which they then relay to the Devs. The Devs obviously look into these reports and come up with some idea of what needs changing, so since there are still complaints and unhappy players because of the same issues NOT being resolved, there's only 2 possible reasons as to why these issues are ongoing:

1. The Mods are just being lazy and not taking note of all the opinions and responses to relay to the Devs, therefore, as far as the Devs are aware, the events are fine the way they are.

2. The Mods are doing everything they can to gather the feedback and relaying to the Devs, however, the Devs look into those feedback and decide "This event is making the most profit so we'll keep that the same" or "This event isn't making any money at all so we'll change it so it does" and finally "Okay, now we have all the spenders sorted, let's get an event out for the Free to Play, but it can't be too good otherwise the spenders will get annoyed and stop playing meaning we lose money."

Now as for the schedule for events, you should take a leaf out of the book of similar games that actually have happy players, release news about events on a MONTHLY schedule, tell us what events are coming out on each week of the month. This way, once you put them out there, there's a full month you have to see were the problems are and to fix them.

As for the server maintenance issue, is it that hard to put an in-game message that says "30:00 minutes until server maintenance"?

Next, for the group wheel, the reason why you got rid of the mood scrolls is because they are something that some players spent money on and so you made the mistake of giving a profitable item away for free. Any who, the rewards from the wheel should correspond to the level of the group i.e level 1 and 2 magatamas for low level groups, level 2 and level 3 for the next level groups etc. Shape shifting card is pointless, coupons are good, dango is okay, the group summoning chakra pack is good since it actually relates to the group rather than having it as a pack in the shop so that the top spenders can basically max out their group summon through money than through the group members working together.

Finally, the ninja puzzles, for F2P, amazing idea, easy, free daily rewards for very little effort, the only suggestion I think that would make it a bit more...worthwile is to maybe have puzzles for more ninjas and add 1 fragment of the ninja who is in the puzzle rather than the coins since coins are VERY easy to come by as most players make well over 1 million in a day.
