"To curb the offensive lane bully play patterns"
What's wrong with lane bullies? Cass was defined as one and we have plenty others that are honestly fine like
etc
If you wanted to balance out Cass's lane bully patterns you should have focused on changing deadly cadence (old passive ) to be less about mana and more about ramping damage. Possibly even retool the purple field thing to goto minion clearing and the other 2 for pure harass. She should honestly always be a lane bully, just like Ziggs and Darius always should stay as bullies. **The point of lane bullies is to win early and fall off late, it's supposed to be a trade off. **
Karthus, Veigar and Nasus are hyper scaling farm champs, Cass isn't.
