well this is for u love:) this work for a vayne support mostly :) also for Ashe but for are you playing with ezrael or corki or mf take a look at the next one :)
and again always remember the shoe's you are buying depend on what the other team have most dmg as. but mostly i recommend movement shoe's :)
so when u look at the other build i made for u there :) thats mostly for when u play vs very fast opponents like ezrael and corki and such as u need the slow from the finished Heart of Gold top make the kill sometimes also its awesome combined with your Ulti:) you see i also changed the build up here a bit, not only do you have the opportunity to chase very well but you also got the slow if needed :)
the one thing you always need to remember sacrifice yourself if needed for the team, don't take kills and ward where it shud be warded! And ofc don't waste your grab!!
