Hello,

first of all, I would like to say that it is nice to have a new feature in the game. Now to the point - you killed the whole feature right after its release.

So what seems to be a problem? The feature - Infinite Illusion was added 9th of September as a part of a common weekly event update. Players started to create teams suitable for reaching high damage. P2W players are obviously in a huge advantage with 10t Madara, but that's not the problem since these players will be always on the top anyway. Problem is that once you manage to get a damage result, you can sweep the instance and get the reward. This still sounds pretty reasonable but wait, there's more: Once you go to the challenge again and manage to deal lower damage, it will overwrite your best damage in the ranking table. That's compensated by the fact, that the best resulting dmg is saved in a form of "sweep btn." so once you have attemps back, you can click the sweep btn. and get your previous best score. That's still not all - you can click the sweep btn. even another week and it still works! That would be perfect for lazy players but there is one more thing which is making it pretty complicated. One week after the release, there was a secret update to the feature which drastically changed the damage to the frog. Now, it is possible to reach 40 - 50 % of the previous damage at max. The reason is that the frog enemy was updated and got lvl 3 immunity which prevents all kind of debuffs like resistance and defense reduction or crit chance reduction (which in the end increased the crit chance for ninjas and made a huge damage difference).

Now to summarize everything I've mentioned and what is the problem:

Some players managed to get huge dmg numbers which currently cannot by reached again due to mentioned patch. The sweep function however still works and it is possible to get the number from before the patch. With such a number, there is no way someone will ever overcome that number. In the end, the feature is just about clicking sweep since there is no way to climb through the ranking, and get the reward every week. Also, once you added the immunity to the frog, there are like 10 ninjas at max, which are able to deal some damage and there is no way for other ninjas to be effective at all.

My suggestion is: (nr. 1 is necessary)

1. Reset top damage weekly, so everyone has to do atleast one challenege per week. (not just click sweep btn. to get the number from previous week)

2. The table should include only the highest number. If the player manages to get lower damage, his position in the table should remain the same. (and maybe add some kind of indication, how much damage was reached in the last challenge)

3. Remove the immunity from the frog so players can try different teams which might be effective thanks to their passives etc.
