What data out there shows that Khalistan is unbalanced?
Don't get me wrong, I want this to be unbiased. I just want to know if there is any hard data out there that shows that she is unbalanced. I'm pretty sure that riot makes a lot of thier decisions for buffs/nerfs based upon processed data (not to say that forum posts aren't good to bring things to thier attention) and not the outcry of the player base. And please don't talk about your personal experiences playing as/against her. Thats just one point of data out of thousands that needs to be put together to show the bigger picture.
Edit: and yes I know it's Kalista. I'm typing on an iPad
