Make Veigar's Event Horizon A Black Hole

New E skill description:

Event Horizon (Maybe even change name to Black Hole) Cooldown: 20/19/18/17/16 Cost: 80/85/90/95/100 Duration: 2.0/2.25/2.5/2.75/3.0 Range: 700

After a 0.5 second delay Veigar conjures a singularity at a point trapping all enemies within a 375 radius for its duration. Not even light can escape the singularity Veigar's dark magic created so enemies on the outside of the even horizon cannot see the inside. Enemies can only see you or an ally on the inside of the black hole if they are attacked from inside it. Enemies on the outside can walk into the black hole but are then also trapped for its duration. The event horizon stop dashes going out but not in. Gravity from the singularity amplifies enemy movement toward it while slowing movement moving away. Speed: +50% while moving toward the singularity. Slow: -80% while moving away from the singularity.

Summary:

Veigar's E would NO LONGER STUN targets that run into the walls but rather provides more unique utility. Enemies cannot see the inside so Veigar has more strategic options for using his E. He can use it on enemies to trap them, use it on his team to block enemy vision, or use it on objectives like baron/dragon. The speed adjustment this provides to enemies makes them more likely to herd themselves to the middle of the event horizon so Veigar's W is also easier to land while giving the enemy some counter-play based on how they move while they're trapped. No one except Veigar players seem to like him having a 2.5 second stun so this could be a fair and fun alternative that provides some more complex counter-play that isn't as simple as "just don't walk into the wall"

Let me know what you think.
