Viegar needs a nerf extremely badly
His trap needs silence removed then he'll be even remotely balanced but as it stands his trap is tremendously overpowered because it silences+stuns and since riot insists on having him be able to 1 shot people he drops insane damage that you can't do anything about. It's bad enough that it zones off in itself so you can't catch him as melee, Even when you dodge his trap if you're inside it you mostly screwed, because he can just combo you into the ground. I had a ton of MR last game and he still few hit me no problem. And having "your team focus him" is not a solution, no single champion should be that powerful. His CDR on his trap is very low mid/late game too with common items.
