Kayle has became so squishy and item needy to win. Her passive scaling isnʻt helping her too. She just doesnʻt do a lot until its too late. I think that she becomes so unreliable until at LEAST she becomes ranged. With how easy to kill she is , she needs to stay far to do something.
I think they should switch the stats of her at level 11 and 6. Make level 6, she becomes ranged and level 11 she gains the flaming waves.
