Veigar's Event Horizon needs a rework
This is NOT a riot bashing post. Be considerate.
I really believe that this ability is currently just toxic for the game. I tweaking numbers will not solve anything for it. The ability needs to be reworked to make it serve its purpose. currently making it stop dashes will make it better than a
ultimate if landed correctly. It is also still a 2.5 second stun at max rank. The ability is still ridiculously strong, its just that the rest of Veigar's kit doesn't work with it. His W doesn't land unless the target is CCed, which doesn't happen now. the cage can trap them easily, but Dark Matter hits such a small area and takes so long to fall that it the target should not get hit by it. (His Q and R are fine, though i would put more damage on his R and take away some from his W.)
Then there is also the point that Veigar is extremely squishy. The lack of instant CC from his E allows people to jump on him and kill him before he can do anything. And IF they are trapped in the center, they can still damage Veigar easily, usually winning the trade.
I do not mean to bash riot by saying this, but not actually reworking the ability just seems lazy to me. People here on the forums have offered so many different views and some are absolutely great (others are.......OLD STUN BACK NOA!!!!!...... yeah). The current E makes is an amazing ability that doesn't make anyone but support veigar's happy, and that was ironically, what you were trying to kill. It doesn't help mid veigar and enemies dont like to go against it. So why not rework it to be a skill shot with travel time or a solid stun. Something like a velkoz E but stunning when it hits. or some other original skill shot. heck, even a not original skill shot. Just something that can fill the role it needs to.
TLDR: The new E is still Overpowered, it just is not good in Veigars kit. Veigar needs a stun, not a cage. You should rework the E because of this.
