The battle with Shin was kind of illustrating that despite being gods, they need to actively use their power to actually BE gods. If they just go around assuming they easily beat anyone, they're gonna get themselves killed. Even healing is apparently a conscious effort (In earlier series Kurama did it for him) as Hashirama could kill himself with a Kunai despite possessing godlike healing, suggesting it was a conscious effort.

Naruto being Rusty is an extremely overrated comment by the community. Kurama was just being sassy. They either should've been more careful to fish for Shin's dojutsu or they should've ended the fight in a single high-power attack. In stead they went soft on the Shins, allowing all the shenanigans that ensued. After all Shin did have a Mangekyou and every single MS user has been trouble.
