General usage and skillbooks.

Kakashi's book makes him sort of useful, also his usefulness in earlier levels is relatively high. We all went through those moments where Kakashi was the all-star.

It's just his clone is pathetic and his growth is a joke.

Kurenai is due to general usage. Her mirror reflects and mystery is good for ranked battle. Slap her on a team and you'll enjoy results. She's *right support right now and actually has pretty good growths.

Shino GNW: Ranked, and Ranked alone. He's a great F2P option to have on a team. Mercury from S99 does videos displaying general usage of alot of F2P ninjas and shows them off quite well. Shino shines in a lot of his videos. Would recommend it.

PB Sasuke: I had him lower than he should have been from the start. He's a good ninja overall, and even better with females. From Ranked/GNW and PvP.

Kankuro GNW: General usage. Arena he's still relatably strong. And pretty ignite happy with his puppet on display.

Although I wouldn't grade him any higher because of the puppet itself as well. High cost to re-summon. But you can build him into some really fun teams with double chase/charka battery
