I disagree about Vayne. I continue to see Vayne players do incredibly well; like Karma, she's just much harder to play.

The main thing about Vayne is Silver Bolts. Because of SIlver Bolts, she does not significantly need attack damage for the majority of her damage; instead, she needs attack speed. Movement speed also helps her, as she is incredibly fragile (even for an ADC) and often needs to be able to dodge stuff during the few seconds that Tumble is on cooldown, especially if she's silenced. The counter-play against her is limited to landing a stun on her - if your team is good at that, then she's not hard, but good luck landing anything against a really good Vayne player.

The problem is that her dependency on mobility and attack speed is rather foreign to most ADC players I've encountered. They aren't used to having to (effectively) blink around in the middle of combat, especially when your passive wants you to just run at the enemy. Most of the Vayne players I see on her Free Week just use tumble as an initiation and disengage move, or else clearly aren't thinking about where they are about to tumble to.

The only issue I can reasonably see with her is, as you pointed out, her single-target nature. The issue there is that any attempt to change it would have to change her mechanical identity, as Silver Bolts emphasizes attacking the same target repeatedly, so I'm comfortable with her current move set.
