If your going to make Veigars E based around caging people.....
Why not actually make his kit designed around using the walls to enhance his abilities? Since the walls are delayed now, trapping someone inside of it should make enemies actually afraid. This would fit his character style of "I was tortured in isolation in Noxus prison for YEARS, now you will feel the pain and suffering I endured!"
Q- If sent through one of event horizons walls it pierces through ALL targets
W- If cast inside event horizons walls it's fall time is reduced to .5 seconds
R- If cast inside event horizons walls it shreds the targets MR
Of course, these are just some ideas for what the abilities enhancements could do. I'm interested in what you guys could come up with for this.
Edit: An idea by Protonic: His ult could "supercharge" the E, causing it to have a echo like effect, that could either damage enemies in the center, or put a static effect on them.
Edit 2: Idea from Verandure: His ult could cause an AOE explosion when cast inside of event horizon. The explosion would be so huge and downright awesome that it would destroy the walls of event horizon. I dont know about you, but I think a ball of pure energy strong enough to turn a beings own power into negative energy and erase them from existance, should have a reaction with a condensed form of the edges of space and time.
