As the description of Nito's Lord soul says:
"Gravelord Nito administers the death of all manner of beings. The power of his soul is so great that it satiates the Lordvessel, despite the fact that much of its energy has already been offered to death."

Which implies that his Lord soul have lost power over the great length of time that he has been "Keeping" it. So Nito, the first of the Dead, is not as powerful as he used to be.

Yup same goes with Gwyn just a shell of his former self. If the chosen undead fought the Gwyn we see in the cinematic of the game then he will obliterate us in a matter of seconds. :P
