Oh boy the enemy team picked Nautilus and I am an immobile melee champion

At least you're melee, so you can tank up. HF being a ranged immobile champion like anivia that he will pull in, interrupt you 3x and then fry your egg and eat it. On top of that, his ult basically summons Vi to attack the enemy.

It's called counterpicking haha.

Maybe don't select the slow, immobile melee champ unless you're 4th or 5th pick, in case they do go high CC and kite.
