I don't get what's so impossible to deal with about Kalista
You run at her at 550 speed as Yi, Udyr or Rammus and still can't catch her. So what. She's jumping away from you, not participating in the teamfight. Your team should win anyway. If she's splitpushing instead of fighting, sure, you can't kill her to make her stop, but you can reach the teamfight faster than she can because she needs a target to jump off of and you don't, so your team should still win the teamfight taking place in some other lane.
oh wait im suggesting an "op" champ isn't actually op pls forgive me gd
