Give Annie the Veigar Treatment
Annie is a champ that can be played mid, support, and even top. The reason I'm saying give her the Veigar treatment is because she also has an aoe instant stun that can completely turn a teamfight around alone. However Annie's combo is nearly fully aoe while Veigar's was mostly single target. Veigar could only melt one person while Annie can melt an entire team. I think tibbers needs a .75 second delay and marker on the location he's being called to provide "counter-play". However, these are only the words of a salty Veigar player.
Edit 1:
I forgot to mention how we should "buff" annie afterwards. Lets take her most simple form of harass being her Q and lets make it a skillshot that can be blocked by minions! This will surely compensate for removing her ability to stun anybody and make her completely viable!
Edit 2:
If the tone of this post doesn't make it obvious this entire post is sarcastic. Annie is fine but her playstyle is very similar to veigar's which is stun someone and burst them down. However the lesser played Veigar is the only one that got completely destroyed by Riot to "compensate" for the removal of dfg while annie and a few other champions received legitimate buffs instead.
Edit 3:
I already posted this elsewhere but a easy fix for Veigar is to make his Even Horizon appear gradually from a starting point and continue around to an end point. More specifically, have it begin at the point closest to Veigar and over .75 seconds it forms around both sides and rejoins at the farthest end. This allows Veigar to punish over aggressive laners and better protect himself while not being able to just insta stun anyone or any team from a long distance away.
I just don't understand how Riot hasn't already tried this or at least made his W land-able on targets trapped in his E. I mean they had to know that Veigar would just become awful with how much they took away from him. It's almost like they put no real effort into making him fair to begin with.
"The Veigar treatment"!? I'll show you, you insolent fools!
