Veigar Buffs - A Better Alternative?

I'll keep this short and sweet. I'm a former veigar main, former as in the previous rework killed him for me. Not only did my win rate with him go from 82% to 44%, but he's just not fun to play anymore. I'm really happy riot is buffing him, but even if these changed go through, I'm not convinced they will make him feel anymore rewarding to play.

So here's my idea: E - Now has an instantaneous slow (~50%?) along the indicator lines. Note: The hit box for the slow would not be lingering, enemies would only be slowed if you dropped it right on their head, not if they walk through it before the cage appears. This is so as to only reward well placed slows and not allow the slow to combo into the stun.

What this does: The slow, given it's ample enough to allow a well placed w to land, now allows Veigar to do his good ol' reliable EWQ combo while still giving the opponent options.

About the current changes: I love the idea of getting AP on assists, now I'm rewarded for leav ing lane to help teammates and not being pressured to try and KS everything. The increased drop rate on W is nice, but doesn't help anything. Now when using it raw, you lead it a little bit closer; it's still not fast enough to be used as a reliable skill shot (and if it was buffed that much, it would be broken.)

Other changes: Can we buff the ult ratio and remove the bonus AP ratio? I know veigar is supposed to be an anti-mage, but all this does is reduce veigar's early game targets and creates an anti-fun mechanic for anyone that builds AP. Revisit the idea of an AP stealing mage with a new champion, it doesn't have a place on veigar's kit anymore.
