I'm going to laugh really hard when the same thing that happened to Ahri happens to Veigar
Changing how Q works even with massive nerfs in other places is going to shoot up his Winrate just like it did with Ahri even though people were crying about the "ahri nerfs" for days then all of a sudden HUGE winrate spikes on patch day. Thats usually pretty rare to happen, but its always Mages that experience that shit for some reason.
**Veigar mains saw his E as Instant Stun with a bonus afterwards. Now its actually what it should have been, something you have to time and position correctly, and they are all calling "mega nerf! wow riot" ** Srsly people
E delay will cause psychological effects and will require actual timing rather than perfected landing.
Q skillshot and range increase allows Veigar to actually farm in bad matchups and allows him a lot more room to poke and trade better in general, something he honestly struggles with.
These two changes alone will honestly have a huge impact on his playrate and winrate, so try to understand oh so upset forums/boards that this is why Riot is skeptical.
