Is a problem, know what'll fix her? +1 second CD on her Q! Her damage is fiiiiiiiine...
zoe's damage is fine,she's a mid laner she's supposed to deal damage (her full rotation doesn't even deal so much damage compared with other mid laners)
her problem is how she apply this damage and how hard is to punish her
edit : it's funny how if you don't follow the board's complain but you try to reason,you get downvoted into oblivion without anyone that can give a answer that's not "you are wrong because yes"
edit 2 :
i heard it seemed like i was defending her,so for clarity that was my answer
i'm not defendig her (i even said many times that i think she's broken,and personally if i could i would just remove this champion from lol),and why you think her full combo means her Q?
i said it many times,her Q and E Q deal too much damage,but her kit in general (so adding her W and P and comparing a full rotation with other mages like you are hitting a pratice tool dummy) isn't too high,so intead nerfing her damage she should lose some of her unneded tools in her kit (e.g. the CDR on her E and/or the trap) and having less damage on her Q/E but more on her W (so she rely more on stealing summoner spells/items and hitting you in a low range dodging with her movement speed than oneshooting you from 800+range,it'd give her a risky and less frustrating gameplay,but it would still reward good zoe players)
just nerfing her damage while it's like the average of mid laners means making her weak (penalizing too much her mains) but keeping her kit unhealty,again her problem is not the damage itself but HOW she deals it (basically only with her Q,an high range low CD and mana cost skill,and with that she can deal damage without tanking any risk from an insane range)
if you didn't get it now,idk how to explain it anymore
