Kalista not complete shit?
I've been hearing that Kalista is a pretty shitty ADC these days.
I played her just today and did pretty well. I personally like to play champions that have decent mobility and don't feel sluggish or helpless when it comes to moving around.
EDIT: Played another game with Kalista
Anotha one
Seems to me like she's actually a very good ADC at least against Varus
