@Meddler, context on the kalista nerfs?
I've always thought that the attack - a minion, keep it low health- auto enemy and rend to deal damage was a hard-to-pull off but rewarding combo. ( Meanwhile MF just auto attacks, and Voila! more damage than kalista's combo)
Kalista doesn't even scale that well... this change hurts her laning phase even more when she needs to get ahead.
If you're nerfing outliers due to their win rate, then
has pretty much never come down from her insane 53% pick rate and 33% win rate
