I agreeThere's never been an arc / time skip where kakashi hasn't shown new feats. Having lost the sharingan won't be all doom and gloom for him. He's still got 1000 jutsu
The series is over since Jiraiya is goneNah he's warming the seat for Naruto.
You can tell Kakashi gives two shits about being the Hokage. He probably has a collection of Make-Out Paradise in his office while Shizune reads it to him.
