Exactly what I wanted to write, only chance they had is to put Zion onto something where he can just own Westrice which is their weakspot anyways. I predict a laneswap from CST as their bot just got owned all the time.
First Westrice tries to dive Zion and loses a lot of HP to the turret, not even killing it. Then TPs and gets killed. Westrice is the WOAT and cost them a tower and gave CST the baron with his play.
