Change Kayle's E
Kayle's E makes it very hard to farm early without pushing and the fact that she goes melee makes her very vulnerable when farming in melee. Before CDR and maxing E you have to time when to use it just to be able to farm, its not like its such a unbeatable ability so i don't get the control on it.
My suggestion is that she should be range all the time and her E toggles the AOE and bonus damage instead of making her range from melee. She is a supportive champ so isn't that dangerous in lane.
