Ask Riot Kalista
Kalista problem is 100% her passive but it's honestly not needed, forget the "unparalleled kiting" and even fates call. You could keep the rend trumping smite and make her more objective focus around dragons and baron.
make rend passive effect her new passive with a cap q can be a short hop + spear throw that does rend active effect without slow e can keep the slowing effect with less dmg
