I'm not gonna lie, I'm an ADC main and I too are sick of Vayne.
Usually you can freeze lane and farm, not giving her a kill you both get farm, you both have a chance of contributing.
However, I advise not to force yourself into a role.. I used to be passionate about learning Jungle.. but it never worked out. however...
I'd wait till the whole "Vayne" meta dies down.. OR!!!
Try something off meta...
I don't own vayne. so me and my friends come up with fun creative botlanes. My personal favorite
Teemo Dinger.. so much Zoning...
Blinds OP
So much CC
Blind and silence while doing tons of DAMAGE
Blinds and silence while being perhaps more Passive..
Oh and one more...

AP MF Support Kalista ADC..
Look up their passives.. Trust me.. it works..
Miss fortiune deals more damage when she hurts the same target...
Kalista... W passive.. Will deal % of health When her and her Bonded attack the same target.. up to 20% health.. (Level W first) get bork and then do 28% health.. almost a 3 hit KO
