Kalista and why u shouldnt be excited

its simple her kit is amazing yea she lacks burst but her utility will be why riot will nerf her over and over till she is to weak to even be viable :(.. its sad cause im excited to see what she can do and just based on her overall kit i know riot will end up olafing her into the ground :(.... when the full numbers are out on her ill test her on pbe and give a better opinion but right now im just scared she will be over nerfed.....
