If Kass wants to stand around and become a mobile Wind Wall, that's fine, as doing that carries gameplay for everyone involved and has appropriate tradeoffs. I also gave Force Pulse a half-second delay and slowed down the projectile speed on his Q, while also making it a skillshot, so he can't negate enemy plays without making a significant effort himself. I made specifically sure that Kass doesn't get to just nullify projectiles at the press of a button, so even if he does block ultimates, it's a difficult and costly play for him to make.
