Nerf Kalista's passive
the infinite dash is stupid, because it lets her dodge every skillshot and harass thrown her way; it does matter if you aim ahead she can just dodge because it has no cooldown. It allows her to easily kite in teamfights causing her to counter anyone without a gap closer on a very short cooldown.
Either make her dash have like a 3 second cooldown, or make her dash not work while she is slowed . Right now she auto kites everything and gets easy poke on anyone no matter how careful you are. She is toxic to play against as there is no effective counterplay to her dash. This needs to change ASAP.
