I love Viktor, he's fun to play, but he needs a hotfix.
His E is terrible as is, because it drops hits CONSTANTLY.
And I don't mean edge of the range, or an occasional bug. Passing right over them, out of, say, 5 or 6 minions, at least one won't get hit. It's really common, really glaring, and really frustrating, especially since it happens to champions too.
