So, why are pro teams.... 5 man teams, trying solo queue cheese and trying it wrong? Cait W start does the job better. If you're playing karma to support the team later, why would you do it? You lose so much taking inspiration, can't proc spellthiefs reliably enough, and the build path is just counter intuitive. It's solo queue cheese, not a viable strategy with her. You take the exploit to exponentially increase a lead in damage and pressure. Cait is probably safer, does more damage, and zones better. 7 minute IE. Deal with that before level 6.
That said, since they're on 9.3, why isn't the hotfix eliminating the klepto/spellthief abuse in effect?
