Alright, so as an ADC main, my champ of choice is usually Vayne. I recently played a ranked game against a Vi who got 3 kills ganking toplane and build a triforce and a dusk blade. Whenever she saw me, she just ulted me which guarantees her Q. Her Q then guarantees her E. With this damage I would just die every time. I really don’t see the counterplay... what do you guys think?
You are meant to stay out of her flash + Ult range whenever her ult or flash are up. Also making buy Ninja Tabi instead of Berserk's and get a Phantom Dancer. Probably won't help because damage is too high in the game, but it is better than nothing.
Even as ezreal i hate vi with a passion, lucky for me zhonya can be put in my build without much loss.
I say stall for late after u get 5 items. You can roll and lifesteal shitloads. Get qss.
As vayne hard divers you cant peel are supposed to counter you. Sivir is an example of a champ that counters hard divers.
Its either your team covers your champs weakness or you pick a champion without that weakness.
Or get 
and then
