I legit never see Kalista anymore.

I've decided to start playing ADC as a change from mid lane, so I went to my collection to see all the ADC's that I own ( I have them all with the exception of Xayah and Kai'sa, being the most broken ADC's from what I've seen, funnily enough). I hovered through all of them until I reached Kalista. That's when I thought to myself ''Holy, where have you been all this time?''. I honestly cannot remember the last time I've had a Kalista in my games but I can 100% say that it was before season 8 and I've played almost 3 - 5 games everyday since the start of the season. I got curious and wanted to see some of her statistics:

JESUS. That win rate is hard to look at. It pains me that one of the most interactive ADC's in the game is doing so poorly. Why should she be gated this far back? Because of the LCS? I can understand why she would be a problem there because Kalista does require good communication with her Support and it makes it even better if her entire team can play around her but what about SoloQ? Why should the average player not be able to play her without having to DuoQ with their support if they want to succeed?

Thanks for reading my post. That's all I have to say about the state of Kalista, I'd like to hear what you think about her though.
