Ekko is the cure for 4 v 5's

my team was a 4 v 5 all match with an afk jg so we were behind when we got to team fights we were ace'd but then after the ace we went into another 4 v 5 and i got a 5 man stun as ekko and we aced them and no one on our team died. because of this we got 2 towers and a drag and then we had the match in the bag.
