Before, Veigars who missed their stuns were dead meat. Now? It is no longer possible to NOT "miss".
I think that's my main gripe here.
I didn't love the old stun. I didn't enjoy how reliant he was on landing the edge of the stun on the target. It seemed like trying to land a weirdly curved "skillshot" rather than trying to lock people up in a cage. But they didn't make it better at being a cage: they just made it so that you no longer could hit with the edge.
The thing about old Veigar was that if you missed your stun, you were instantly obliterated, and people made fun of you for being trash.
It looks like the thing about new Veigar is that you always miss your stun.
