Would Nautilus Make a Good Support?
After looking at his abilities, he seems to share many features with another common support, Leona.
They both have gapcloser abilities that briefly stun the enemy (Nautilus's is longer and can be used for escaps, Leona's works through minions). They both have defensive steroids and the ability to damage nearby enemies (Leona +resistances, Nautilus +shield and a slow from riptide) They both have on-hit stuns/roots (Leona shield bash, Nautilus passive) They both have AOE disable ults.
So Nautilus worth playing as support?
or other ADC who can kite well.
support during this free week (just a couple of times though) and he's good. He has so much CC that it isn't hard at all to save your ADC or lock down the enemy ADC. He has a great deal of mobility with his hook, if you get caught alone you can dash long distances by hooking walls, or just sit right next to your target and nail them to the floor.
