how the hell do you win against a vayne
seriously she basically wins lane with her 3 hit true damage auto bs. she has a self peeling ability for ganks and dont fucking say "just focus her" and act like the rest of her team is ignorable no, they arent, you focus her , her team kills you, you focus any of her team, she kills you, she is so fucking toxic and impossible to beat and you cant counterbuild her because of her bullshit %health true damage WHICH SHOULD NOT BE %HEALTH AND BE A LOT LESS TOXIC IF IT SCALED WITH AD, holy shit shes impossible to beat, fuck vayne and her op bullshit roll invis true %health true damage knock back
. They will bully her out of lane early, denying her farm and items and just make her life hell when she needs to be building up for late game. Obviously that doesnt mean you can play stupidly , avoid standing near walls and ward extensively because you may be camped by a smart enemy jungler. Focus on reliable csing while poking her down. Out-buy her in items early and press your advantage trying to secure a kill or two if possible. Midgame focus on rotation and objectives. Most Vaynes will stay in lane and try to farm up in the time you've left for them but it wont make a difference if they have no towers left. From there it should be a pretty snowbally win where the Vayne is too far behind to help her team and you can just steamroll through to the nexus.
. She's easy to zone out and loses a lot of DPS if she has to switch targets, meaning if you have a decent team comp which is admittedly rare in solo queue, it's possible to deny a lot of her silver bolt procs.

or Lose
combo now can't be QSS'd; He can just flash through your team, become untargetable, nuke you to nothing, and swap back before your team's CC lands. Either you are in range of that, or you are so far away your team is fighting 4v5 without an ADC.
