I just played against a Veigar.
I was going Zed, in a normal game. At first he was throwing some decent harass and staying alive quite well, dodging my harass.. I thought "Hm maybe new veigar isn't so bad."
(Skin this part if you don't want story time)
At level 3 I changed my mind, I started throwing my regular WEQ harass while bullying him away from his farm as you're supposed to do in a Veigar lane especially when you have the early-game advantage like Zed has in lane.

After level 6 it was so easy to outplay/bait his stun, I could one-shot him after being 3 - 1. If he even showed his face i'd be able to turret dive and leave with 50% health, and thats when I messed up. Veigar only got ONE kill and that was a lucky stun he landed while sitting in a bush, where he got his full combo on me succesfully and I was somewhat near 70% health. I complimented him but even after that I had a considerable lead and could 1v3 with their lack of a tank.
That game was so easy for me.
(Now for some decent Criticism. )
So the main flaw I noticed with the enemy veigar is that he wasn't very good at predicting where I would walk, in fact he played like Old veigar where you point and click your stun. He started adapting but even while trying to predict I had good enough reaction time to step out of the way then W my way to safety and leave his range.
Holy crap though that buff to his range made him way better at zoning out is opponents.** I think Veigar is heading in the right direction but Riot has some work to do with him, right now he's in a pretty toxic spot for people playing as him, and against him.**
BTW DJ sona was in that game, sick as fuck man. I love that skin.
