I won't be surprised to see Kalista in competitive again next patch
Her winrate has risen up close to 46%, and shes already been played in competitive and won games, and the PBE buffs to her Rend are actually really big, her laning harass is back now and not killing someone with E is not that bad anymore. Please Riot, if she does become strong, don't just nerf her insantly. Shes been absolute trash for a while, let her be in a decent spot for a while.
