True. It seems the potential of a transplanted rinnegan is heavily limited. It seems though that it gets better with time, as Nagato was clearly more proficient with it (but also had it for decades rather than weeks or so).

Hagoromo is a big unknown, mostly because we barely saw him do much. But he was able to call souls back from the dead, which is a power i've not seen any other Rinnegan user do.
