Possible Veigar Changes?

Heres my thoughts on Veigar. He is good, pretty good, but he isn't where he needs to be yet. He stomps noobs, but he gets a noticable bit worse once people learn how to play against him. Thats like every champion except that Veigar is instantly made a lot worse by picking an AD Mid, making him a niche pick. I like Veigar's identity as THE burst mage personally, not the AP Crusher. His W could also use some changes by a little bit. A LITTLE BIT! Here me out.

Base Stats

• Base Mana Regen. per 5 increased to 9 from 6
• Mana Regen. per 5 per level decreased to 0.6 from 0.8
• Base Armor reduced to 20 from 22.55
• Attack Range reduced to 500 from 525

Base Mana regeneration buff to help his early game mana and a mana regeneration per level nerf to make him not go insane late game. Some slightly stat nerfs in order to put more power into needed buffs.

Ability 1- Baleful Strike

• Now applies 50% normal spell vamp from 33% spell vamp

This has bothered me. Why does an AoE spell that can only hit two targets apply 33% spell vamp? This should go for every 2 hitting spell.

Ability 2- Dark Matter

• Lands faster based on distance from Veigar, ranging from a 0.625 second delay to 1.625 second delay
• Now has a more clear warning indicator, showing the AoE Radius; a purple (or green depending on the skin) circle will shrink towards the center of the indicator to show when the damage will be dealt, this way the opponent can know how fast it will land how fast they need to dodge

When Veigar lost his instant stun, he lost a lot of his ability to deal with Assassins or Fighters that can just instantly hop onto him, namely Zed, Wukong, Kassadin, and the like. Making his W come down quicker based on distance would benefit him a lot. It also comes down slightly slower at maximum range as a slight compensating nerf.

Ability 3- Event Horizon

• Now reveals the area inside of it and the edges once active

I don't see why not. What is the point of trapping someone when a bush can save them if you don't have a ward and that happens more than you think.

Ultimate- Primordial Blast

• Removed damage based on 80% of enemy's AP
• Increased AP Ratio to 125/145/165% from 100%
• Base Damage increased to 300/400/500 from 250/375/500
• Range decreased to 600 from 650

As I stated before, Veigar doesn't need a duel identity. Thats part of the reason he was nerfed, because he had super burst and a super long crowd control. Which should he be known for? Veigar should be a burst mage feared by all, not just AP users. And yes, I know a fed Veigar deletes everyone, but what fed Middle Lane Assassin doesn't? I also decreased the range to help make the ability not seem like an instant ADC delete. Something like this would have to be tested however to see how it would go.

EDIT: Small ultimate damage nerfs from the first, namely to Levels 1-2. Increased the delay on W when close to Veigar slightly, decreased the delay at long range slightly.

EDIT: Baleful Strike spell vamp change and base stat nerfs to make the buffs be able to stay where they are. Reduced W close range delay to before.
