As nice as it is that he finally has 2 sharingan en probably will go beast mode, it is like bullshit that he can use perfect susanoo.
With his stamina he shouldn't be able to use the ps for too long.
By the way i think after the war kakashi's sharingan will lose their light and naruto'll give him normal eyes, or recover them.
I seriously think that kakashi's perfect susanoo may make kaguya dance for a while, because he said HE'll orotect the world this time, so he has some tricks up his sleeve.
