Is Zoe OP?

I have over 200 games with her and she is not OP.
Well, sometimes you can get very lucky in your laning phase if you get a lot and good bubble minions which offer a nice summoner spell.
But you can easy counter her if she uses her ult.
She will always come back to the first portal and it is pretty easy to snipe her with cc then.
And yea it is hard to play her against champs like Shaco, because she dies pretty fast.
