Ekko Gameplay! *feedback please*

Hi ekko main here :) I am not a very good player but I hope you can still take some of my suggestions. You could do with a better build, morelonomicon is not that good on ekko. You should first start protobelt then build lich bane. You can start lich bane and then proto if you want but that is personal preference. Another important item is zhonyas since its active is very good with ekko's abilities. The other remaining items are probably just situational. I like to go rabadon and other good possible items like void staff, ga and banshee
