My opinion on Kai'Sa AKA the new Void ADC champ
Disclaimer I only know what I've seen at the time of writing this Honestly I don't think she's "that" bad. Numbers on the PBE might be to high but personally I don't think her kit is that bad by its nature. At worst I think she'd be somewhat similar to release Camille strong but still beatable. With some niche uses that would stay after nerfs (raw pick potential for Camille raw variety in build for Kai'Sa) Since she can scale off pretty much every offensive stat (like Jax actually) but yeah I think her kit is actually pretty good and I personally think she wont be half as bad as Zoe (who SMH is probably gonna have her legs arms and ribcage shattered at this rate)

which synergize well with her kit.
