Veigar's Stun

Just gonna make it quick and concise. Veigar NEEDS an instant stun with the current champions that exist. It's simple, if he gets caught he dies. It's already difficult enough to land his w, unless someone is chasing you and refuses to respect the amount of damage that it does. I'm really afraid that adding a 0.75 delay on his e will be absolutely crippling. This is obvious during the times when you miss the instant stun while playing veigar. Do you actually feel safe with someone locked inside the event horizon, instead of stunned with the edge? No. Veigar's range and health pool are so small that even if you manage to lock someone inside your e, they may very well kill you before you can kill them, unless you're very fed. Please leave an instant stun with Veigar's event horizon. How about this? Event horizon is still instant cast, without a delay, but now ONLY stuns the CLOSEST enemy champion to Veigar. All other champions caught by the edge are slowed significantly. Lemme know what you guys think.
