So i am currently a silver player who currently really enjoys playing Vayne. I only starting playing bot lane about 2 months ago but i think I've got it all in a nutshell. This build can fit every type of team composition or opposition builds.

In lower elo, statistically speaking your supports aren't always great. To make good out of bad i like to play a certain play style. I like to stay back and farm if i can tell that my support is not good and i don't feel i could depend on him to pull something off. I like to take free condemns, proc the silver bolts 3rd bolt and get out. In other cases you may want to all in if you feel you can kill one or two enemies.

Farming as Vayne can also be mentally challenging. I still do this, but a lot of Vayne's like to think they should proc there silver bolts. NO. Do not think this. Farm as if you were a ADC with no 3 hit passive. I like to use my silver bolts to my advantage when farming. Silver bolts can make hitting cs a lot easier and cannon minions are much easier to get the last hit on if your support does not have relic.

Take in mind what items your opponent has. If your opponent obviously has better items than you, try yo stay safe unless you get a really good engage or free poke.

This is where Vayne generally starts to shine. She scales incredibly well into late game and can solo carry alot of this teams in this time. This is where you either want to come back from a negative laning phase or snowball.
