Why I think Zoe is weak currently
The biggest complaint I have about Zoe is her W. Yes, while it allows her to cast summoner spells without a theoretical cool down, it actually limits her kit to 3 spells. her W serves as her ult because of how long it actually takes to collect a shard and a useful shard instead of getting Smite, Clarity, or non-useful situational spells. Yes there are times when you get decent summoners consecutively, but there's times that only useless summoners shows up. I think in her current state, even LB is stronger.
