Lol I loved getting Rylais on Viktor because it was busted AF. You could just infinitely kite melees around with it. And kill dashless champions with nothing but your ult. Obviously it totally needed a nerf though.
The point of the mini-rework was to tone down his 1v1 burst, and make him more team dependent.
Which is frustrating. I've been playing Vik since S3, and his burst was always what I found fun about him.
But, making the second E tick less reliable is very much in line with Riot's apparent design goals for him.
He'll still have massive Q burst; it's just riskier to apply.
I do hope Riot keeps an eye on him though. He's not a Nidalee or a Lee Sin--he's not that flashy or fun to watch, so it seems unlikely that Riot is going to go out of their way to watch out for him. If the Rylais nerf hits him hard, he could definitely end up in the dumpster for a couple months. It's happened before.
