Veigar Moving Forward (Rework Idea)

Obviously Veigar is significantly weaker than last patch, however, I completely understand why they had to nerf his E so hard. His E was very strong, arguably too strong, and because of this Riot can't exactly buff him without worrying that he'll become far too powerful. I've come to the conclusion that he can't exist in a good spot with how his old E worked, he needs a new identity. I think he would fit the role of control mage more, something akin to Orianna.

I have a sort of rough idea of what I think would be a lot of fun: (not good at coming up with names)

• Passive - "I will swallow your soul, or something.": Enemies killed by Veigar within his Gravtiational Anomaly, or Black Hole restore a % of his mana, and grant him additional AP*.
• Q - ???: Sends out a fast moving skill-shot, dealing damage to all enemies it passes through. Reduces in effectiveness and speed for each enemy hit.
• W - ???: Sends out a slow moving skill-shot. Upon hitting an enemy, or reaching its max range, it explodes, dealing damage in an area.
• E - Gravitational Anomaly: Creates area of strong gravitation at target location for a few seconds. Units within area are slowed moving away from center, and sped up while moving toward center. Veigar's projectiles near the area accelerate** towards the center, and are increased in effectiveness.
• ** R - Black Hole**: Transforms Veigar's active Gravitational Anomaly, replacing it with a Black Hole. Enemies within the Black Hole are pulled towards its center, and are slowed 100% for its duration (not rooted so they can still blink out). While active, Veigar's abilities are automatically fired towards the Black Hole's center, as well as increased in speed and effectiveness.

I think with some work this could be a really fun, unique kit.

*Not sure if 1 AP would be too much, or too little.

**Acceleration could just be a simple vector calculation (upon first entering the area) to change to projectile's speed and direction, instead of actual acceleration.
