The worst kind of team is one that has no balls
You have Riven.
You have Akali.
You have Lee.
You got Graves.
All you have to do is just hop on someone. Doesn't even matter who. Just don't wait to be poked to death and then go in 1 by 1 at half health, then complain about why you can't win a fight.
Sometimes, you have to wear your ovaries on the outside and go hard.
