Pass this on to the developers and ask them to be more agile, they take time to create ninjas and update systems, in addition to the delay in arriving some bt.

New ninjas:

-Dosu, I see part of the community asking, I don't mind not having it in the game but I think they should do it precisely because it has Dosu Npc

-Sakura, in the anime Sakura is a main character that in the game has no visibility in the meta, just create a Sakura that can be euta like Tsnudade.

-Madara, a version of madara without clothes and without eyes, was when in the anime he fought the bijus, sasuke, naruto and gaara. It's a really crazy version of him because he just couldn't see it.

-Sasuke chakra of the bijus, when he fought against naruto, the current sasuke in the game is very weak, there is nothing interesting.

-Kakashi hokage, there are all versions of hokage only kakashi that doesn't have one

-Kaguya, should be in the game by now.

-Hagoromo, must also already exist in the game.

BT suggestion:

-Ibiki, is an old ninja with a good kit but it's not that absurd, his skills can easily give you a chance to have a BT. He could have immunity to Status, Cell Damage from Mystery, Scaling Attack and ninjustu, and buff to increase passive damage.

-Kakashi summer, see another ancient ninja who clearly deserves a bt, reset mystery, improve attack scale and ninjustu, give any new stats he might cause.

-Pain Chikushodo male, a ninja who has 1 year in the game, his kit is nice but nothing extraordinary, clearly he should be a meta ninja and stronger.

-Sasuke Susano, another ancient ninja who deserves an awakening, is a ninja that has been abandoned but must be used.

-Itachi Susano, another one who can have extraordinary abilities if he has a BT like Shisui Susano he can be revived in the meta.

-Shisui Kotoamatsukami, deserves a bt, it certainly won't be that extraordinary, but it would be nice to have one for new players to have more options.

-Hiruzen Edo, is a ninja who is still very good, but all the other hokage woke up except him.

-Kakashi Susano, another abandoned ninja that deserves to be playable, must be an awesome ninja like in the anime, with an awakening he can be a meta ninja.

-Minato Jounin and Hokage need a bt.
