Riot, I never really question your changes, but I want to understand why you nerfed Zoe into oblivion??? Your logic in nerfing her because she was too strong. It’s not okay for Zoe to be able to burst people, all the while we have a Veigar that does the same thing easier....
Veigar doesn't burst people from fog of war.
Veigar has no mobility, not even a pseudo mobility like Zoe's.
Veigar typically needs to stack to become capable of 1shot.
Veigar's ulti requires someone to be somewhat low to execute them. Zoe can 100-0 you with a single spell if she's fed enough and if it's a max range Q.
Veigar's W are delayed right in front of your face so it's very possible to dodge them (though dodging in the cage can be sometimes hard depending on the situation). Zoe's dodging window is less since the delay is played off-screen and off the vision range most of the time, or at least after the first levels in laning phase, and you only see it when the spell is already in your face.
Veigar's CC doesn't last 4.2 seconds in total. Zoe's does with 2.2 seconds of slow and 2 seconds of sleep.
Veigar does not have something as impossible to balance in his kit as Zoe's RNGesus W.
.....
It's not like Veigar doesn't have problems, mostly around his E. But he certainly has it less than Zoe.
Veigar has short range, with no mobility or ways to dodge abilities (like Zoe's Ult) and has delayed CC. If you can get to him, he dies really quickly as the only thing he has is his cage which can be blinked/flashed out or just walk out before the delay ends...plus if you do get hit with his stun, his burst comes from his Q, W and Ult which all have generally short(ish) range so its very risky for him to get close to use it.
Zoe can throw out her bubble from very far range which even go through terrain for even more distance and then ult forward and Q which together is like 1000+ range. All of that while basically being so hard to punish her for it as she'll return to her original spot of her Ult even if hit by CC, so unless you have some one waiting at her original spot OR can burst her in the 1 second she ults forward, she is very hard to punish for doing it (Also having very low CDs so she can easily just spam it). Also it could be the success of LCS as well, as she is almost like 100% pick/ban, there has only been maybe a very few games where she wasn't touched in champion select (At least in NA and possibly EU)
Now I'm usually one to complain about Veigar myself as I really don't like him either and find him really annoying (Though I don't really consider Veigar broken or needing nerfs and the only time I REALLY hate him is in ARAM) but Veigar has a lot more risks for him to get off his burst and the only reason I'd even say that Zoe might have "harder" time to use her burst is because it's all skill shots, but her entire kit itself gives her way way more options and was overloaded.
She needed nerfs. Now the amount of nerfs she gotten was to much but Riot will buff her back up to a more...reasonable level.
