I main Nautilus, i love him as a champion and his concept which reminds me of Bioshock.
But seriously, whenever i pick him, i feellike i always counterpick myself. His shield (which was his main damage) is absolute garbage. I can only rely on E for some dmg. I know he has cc but many other champs (Tahl, Voli, Xin, Thresh,etc...) have tons of cc yet they do more dmg
What type of CC does 
have compared to 
..... Nautilus out CCs him by 12 on a scale of 10. Of course you don't do that much damage as because you are probably support and his W is pretty decent IMO.
I think Nautilus is in a good position right now. He has one of the highest win-rates for a support right now.
nauts w is one of the better shields out there and 3rd form of aoe damage
Any weak champion gets the support role. Nautilus is supposed to be jungler, not support
So i have a cool ap/tank set for jungle Nautilus 
i am a 420k mastery Nautilus S5 right now Nautilus Mastery My wins
