Well, part of Teemo vs melee match-up is that he has a blind that punishes engages and he has a good disengage. Plus the extra damage he gets on the occasional harass. Still, it does come down to, "Ranged vs not ranged."
As for a Quinn build, I'm not sure yet. She has Bonus AD Scaling everywhere (50% Passive, 65% Q, 20% E, 50-100% R) so she benefits a lot from raw AD. I can't help but feel that BotRK may benefit her kit more, though. Part of me just says that because BotRK getting retuned to an ADC item + releasing an ADC however so hey!
Essentially, looking at BotRK | BT with some other item (Zephyr if BotRK?) with belts everywhere else to make the best out of her ult (aka, not melting instantly). Trying to go full-on glass cannon out of top lane could work I guess depending on how easy she controls the lane without any kind of bruiser items but I'd say there's better glass cannon assassin top laners to use (aka, just force Kha'zix through the draft).
My first plan is to see what I can do with BotRK + Warmogs + Zephyr.
