You're talking like you're a pro and you know everything, and you're talking about "Low Elo players" and talking about your criticisms of low elo players, and yet you're a low elo player.
Its quite easy to sit back and come up with hypothetical situations about why a champion can be/ is good, and hypothetical situations where a champion can't be/isn't good, and make assumptions on what players did and didn't do, or what players should and shouldn't do, but all of that stuff really kinda goes out the window when you actually get into a game and get into the moment.
The fact of the matter is that I know all the things you're saying, and while most of them are true, and you're a talented and eloquent writer, everything you're saying is circumstantial and unsubstantiated.
In the broader stroke of things, as a generalization, Zoe feels bad to play against because her bubble leaves little to no room for counterplay in about about 50-70% of situations. You don't see it coming, or it comes so fast you just plain don't have time to react.
There is no such thing as a perfect player. I'm not, you're not, Faker isn't, nobody is.
You're coming up with all these scenarios and "what ifs" and "you should, you shouldn't" claims, and that's all fine and I'm not disagreeing with you on any of it - but I'm saying when the situations come up that I'M TALKING ABOUT, you basically just feel helpless - and not because she played well, or you played poorly, but because there was literally nothing you could have done to stop it.
You can't NOT walk around the map. You can't NOT venture into unwarded areas (how do you think wards get there in the first place?). You can't just stand on your fountain all game long and expect to win a match.
So yes, while all the things you say CAN happen, and we can sit here all day and come up with imaginary scenarios on how to PREVENT them from happening, the fact remains that you can't cover every base all the time in every game.
In those unfortunate situations, its pretty unfun and unfair to die to something you never even had time to react to, and never even saw coming. Namely, Zoe's bubble.
If I walk into a bush and there's a Zed there, I have options. I can flash. I can barrier. I can try to fight him. I can use some kind of ability to do... I don't know... something. The point is that I have TIME to react. At the very worst, I die, but at least I know I died because I face checked a bush and zed was there. I saw zed. We had a 1-2 second little skirmish. I had options. None of them resulted in me living, but at least I got to DO something.
If I am arbitrarily walking around the map, and get hit by something I never even saw, from a champion I never even saw, and all of a sudden I'm stunned (sleep) and don't even know why because I never saw it coming, and then I get 100-0'd by her without ever even seeing her, or what killed me, or ever even having time to react, because I don't even know WTF I'm reacting to, and I have to refer to the "Death Report" screen to see WTF even happened....
That's pretty busted.
