Veigar Rework

I hope Riot would read this if it is possible.

I've been taking some research on what the new Veigar Rework would be. But I'm just wondering, is it really true that his Baleful Strike (Q) and his Event Horizon (E) is being changed, as in his Q is now a skill shot and his E now takes time to be casted. He is already weak early game, why are the reworks focusing on lowering the uses of Veigar. As in, his E is the most important spell that every Veigar needs before he is easily shut down early/late game. *My only problem is that he is already easily countered by the Banshee's Veil *, now the changes are making it worse by lowering the chances of Veigar from bursting his target because the target could stun him immediately, dash away from the stun, or kill Veigar before he could even do anything due to his range (and yes, I do see the changes where his Q has a higher range but that doesn't change the fact that he is a squishy mage that is easily targeted, and needs to reach the AP casters or the squishes because his weak early game made him weak enough to not be able to take out the front lines).

All and all, I'm just curious on why the changes on his abilities (especially his Event Horizon).
