I just played with a Botlane (carry role) Nautilus

a Baut Naut a Boat Noat a Butt Nutt a Bought Naught About Not

Anyway I think it was pretty good. He outfarmed a vayne in a plat game, built AP, fed said vayne then completely invalidated vayne past laning phase. It was glorious having that much CC on the team. For what it's worth, it worked well.

Kudos to you crazy tank carries.
