Zoe

Not here to say she's OP. Here to cover a few things about her.

One: she's Nidalee with no escape. Her only "escape" is a temporary 1 second (unless she has flash which what-the-hell-ever, everybody and their mother has it) teleport - not even a blink. It will return her to her original position every time. Ergo, the way you demolish the giggling little shit is to dive her. Hard. When you see a Zoe, taking a tank like Sejuani or Nautilus or a bruiser like Vi or Warwick can force her to have to be insanely safe or die - and if she ever misses that bubble, the vast majority of her real damage is now gone. It's your time to engage on her. Remember: she's Nidalee. Meaning the further away she is the more damage she will do. Get close.

Two: if your teammate gets nailed by a sleep bubble - unless it's a tank - stand in front of them and take the shot. Zoe hitting someone who's sleeping causes them to take bonus true damage, which is the reason you still blow the fuck up while building a power/defense item versus a straight defensive item with health. Before people start saying that's absurd and OP, keep in mind this is to keep Zoe relevant against things that aren't just full squishies - if she only had these two abilities to rely on for damage against someone building resistances, she'd get basically nothing done. And her combo isn't quite so spammable as Nidalee's goddamn spears used to be.

Three: this is more a comment on her balance - the only thing that makes literally no fucking sense is the last part of her E: that she gets cooldown reduction on her E for hitting somebody with sleep. This means that if you end up accidentally stepping on a bubble you didn't see or if she builds enough base cooldown with her bubble traveling far enough, she can actually chain this stupid ass ability on you before you can actually respond - for a grand total of 4 seconds of not fucking moving and waiting to be blown up. And you thought Morgana was obnoxious. I can not for the life of me understand why the ever-loving fuck Zoe needs an additional reward for hitting her CC. Literally - and I do mean literally - no other champion in the game gets bonus cooldown reduction on a hard crowd control ability for hitting an enemy with it.

Four: Another obnoxious thing: cleansing the "drowsy" effect will still cause your champion to fall asleep anyway. This is just fucking stupid period. If I'm no longer drowsy, why the hell would I just suddenly go into a goddamn coma?

So that's it. To sum up:

To play against Zoe: charge her and protect your sleeping teammates.

Stupid shit in Zoe's kit: Cooldown reduction on her E for HITTING A FUCKING CHAMPION WITH IT, cleansing the Drowsy effect doesn't prevent Sleep.
