What a fucking ignorant and presumptuous post. I have played Cassiopeia since Season 1 and I recently got my smurf to Diamond playing only Cass with a 60-24 record. I know how she functions moreso that you can ever hope. A correctly played Cassio has absolutely no losing matchups; it doesn't matter if you can dodge some of her Q's because landing just a few is enough to apply incredible zoning and kill pressure, and this is especially true pre-rework.
Your garbage list of champions whom you think "counterpicks" really shows you have no clue what you're talking about. Yasuo, Talon, and Ahri all lose to Cassio and Akali just straight up gets destroyed.
You don't know how Cass works and you spat out such a shitty argument and randomly assumes that my incentive has anything to do with counterpicking. You're the reason why we can't have intelligent discussions in and why willful ignorance badly contaminates this community.
Like I can't even begin to understand why you even brought up anything about counterpicks. In fact, I see these types of shitty arguments coming from low Elo players more than anyone else.
If you don't know much about Cassio, don't bother making any claims.
