So when's the new marksman (Quinn) update?

I'm finally going to cave. I'm a mastery 5 Quinn main. I've taken her as my star marksman botlane for as long as I started playing her. For the most part I've claimed that Quinn was in a good place when you get to master her.

Maybe it's my MMR rising into higher level play, or maybe it's all these new champions like Kindred that are performing strictly better than her, but I'm having a harder and harder time achieving her late game fantasy.

I can go 6/0 to the mid game and not give my lane opponents a single kill. But as soon as late game arrives. I just can't do the damage that a vayne or a kindred seems to provide during a team fight.

My auto range only lets me attack their frontline, who's usually a hyper tank. And if Thornmail doesn't kill me first, chances are I fail to kill the tank by the time the rest of my team dies to their marksman.

Blind is an awful bit of soft CC. There's so many "On hit" procs these days it might as well not do anything late game. Like for some reason a falcon gouging the eyes out of his victim still allows them to hit me as long as their weapon is glowing?

But the main reason I'm complaining, is that Quinn's identity as a duelist, her big shtick that separates her from other team fight oriented marksmen, isn't nearly as strong as it used to be.

Used to be, if I see someone squishy or low on health, I could ult half way around the map, find them, CATCH them, and kill them in one full burst. I can't even do that anymore. So many movement items and dashes basically make it impossible for me to catch anyone when they're alone, and if I do go into duel mode, they pop some crazy passive which doesn't let them die, or they simply out duel me.

QUINN IS THE ADC DUEL ASSASSIN! HOW CAN I NOT DO ADC ASSASSIN STUFF??

Riot, please give her the Ashe/Fiora/Juggernaut treatment
