Kaisa has only 500 attack range and no way to kite meelee champions.(Vayne has tumble and E,Xayah has root,Lucian has dash) Kaisa E can be used for kiting but its not a dash. I think giving a slow on her W like Jinx W would be a quality of life change since Kaisas W also has a fairly long cooldown. I believe short range champions should have effective kiting abilities. Suppose a Malphite jumps on me and i don't see how am i ever gonna kite him. Maybe add a slow removal like Garen Q on Kaisas E or add a slow on her W.
