Independant Champions

Hey everyone,

Just need some advice on champions.

Most of my friends are newish, with the rest being low bronze. Unfortunately for me this means they are loath to act like a team and have low map awareness. I have most champions, but I need independant champions that can go in, get a pick and get out as my friends are often slower than a college on a Sunday to respond to ganks or provide them.

I have been practicing Ekko, Kat, Yasuo and Fizz but am fully open to practicing and learning new champs, any advice?
