It's enough to cap the amount of people per battlefield to 30-36 to get it.

Honestly speaking what should be done right now in game is the exact opposite of what the management tries to do (daiske is the only manager that talks with us once in a blue moon, the others are mods that know nothing and have no right to choose anything).

As Garv said before the game currently has a serious problem and is linked in a very large part to how iniury stat works.

To actually seriously rebalance the game what should be done at this point is to make easy, extremely easy, to get level 10 refinements, level 12 runes, level 9 charms and level 9 ba in all the 4 moves and just leave the difference in secondary stats to treasure tools and further progress in ninja assist/myoboku cultivation/summon cultivation/nature chakra.

At the same time you should open kage ti hard mode and let everybody get their chance to reforge tools with +4 elemental resistances and eventually heavy damage reduction tertiary substats.

At that point you should add a way to increase PRIMARY stats, and if that thing is expensive is fine.

90% of the people is tired of being compelled to overstack 1 move and to have no choice but to go for heavy buffing teams because healing, shielding and defensive teams are in no way viable due to how easy is for the enemy move 1 even at comparable power to annihilate our move 3 and 4 (thanks fully on how injury works).

You think whales want to be able to kill people fast and this is fine, but why they may be able to do it by spending this low amount?

Isn't better business wise if they are compelled to spend as much as move 1 also for move 3 and 4 to do it?

And isn't better if they have to go for 4/5/6 different stats instead of only 1?

Btw,that said, limiting our options by making ninjas this expensive and trials/breakthroughs too makes no sense because you are imposing on us to choose between power and lineup options even if we pay.

P. S. the only current level cap you may think to increase currently is magatamas (from 9 to 15 could be fine) and BA level one (from the current 27 to 36 or 45).

Increasing the cap of secondary stats linked features is in no way useful nor required currently.
