@RIOT, Veig E Suggestion!!!
So I was thinking. What if Veigars E was an actual skill shot, but worked similar to how Fizz's ultimate works.
Veigar shoots a projectile, if it hits an enemy champion it stuns them, and explodes in an arc behind them, forming a circle with them on the edge of the closest to veigar, OR if it reaches max range it explodes in an arc, forming a circle, with the closest edge to veigar being the point of the explosion. And stunning any one else in the arcs, or who try to pass through the arcs. And the walls would last the same amount as they currently do, as well as stun for the same duration. ** (See attached drawings please)**
Doing this would create the counter play that it needs, and still make it a reliable spell.
