How to Separate the Good Veigars from the Amazing Veigars

So first of all, I don't main Veigar or anything, but with all the disappointment surrounding the recent Veigar changes on the forums, as well as playing against a few Veigars myself, I've come up with a possible solution.

I think much of the controversy is built around the changes to event horizon. It was a pretty iconic ability in Veigar's skill set. When used properly, it has little counter play as it is instant, and serves to set up the rest of Veigar's combo. By introducing a delay to the ability, you add counter play, but also really screw up a big part of his kit and identity.

So here's my proposal: Make event horizon instant for the first target it hits, and if it his multiple target, the champ whose center is closest to the horizon gets locked down. After the first target, the spell continues to charge up for .75 or .5 secs or whatever before coming into full effect. This effectively stops Veigar from instantly locking up an entire team with a non ult ability, yet still allowing good Veigars to snag the target they are aiming for. Veigar was meant to be a single target burst mage anyway, this will add to the theme while still allowing sufficient counter play. What do you guys think?

TL:DR - Let Veigars stun be instant on the first target it comes into contact with while still having to charge up to stun any more targets.
