However, bodies could be granted whatever power Nagato wanted before they were taken out, e.g. Deva is shown summoning when Gaara is being sealed. There's no particular reason why a specific body had to have a specific power (since Human Path changed bodies).

Power between the Paths was also shared, e.g. the paths needed all to be taken down for Deva to cast his konoha-crushing attack. Cooldowns however are limited to that specific path (e.g. only Deva was powerless), meaning that the best strategy for Nagato is to specialize the paths.

Lastly, we never figured out whether the power Nagato imbues in a path is still his to use. Can he use Deva path when it's out there? We don't know, but i would find it extremely unlikely that Nagato would spread the power to the paths exclusively and leave himself completely open (if this were true). Meaning, it's likely that the power to use normal ninjutsu (as well as other Outer Path abilities like Rinne Tensei) were reserved for this personal use.

So to me, it seemed to largely work as advertised.
