Vayne problems:(please read)
her passive allows her to keep chasing the enemy too easy in the early game for example if an alistar uses his combo and the enemy has to retreat they simply can't and this passive allows her to hit the enemy 3 times too easily making her even better in the early game maybe make her passive scale like 10 movement speed until liv 6 after six she has 20 ms boost and at liv 11 she has 30 ms speed boost.
Her tumble allows to escape the enemy ganks or avoid deadly hooks too easy this is an other reason of why her early game isn't as weak as
on of the biggest weakness of vayne is the enemy poke but unfortunately she can avoid skill shots too easy with this skill,vayne gets her spike when she has
when she has this item she becomes pretty oppressive and is not exactly what hyper carry means,vayne not only counters tanks like shit but is op against squishes as well or low mobility targets not only you can't run from her she will be stealthed dealing a ton of damage each hit,for example when draven gets
he will be good only against squishes but still weak against tanks,while vayne gets op against almost everything
aura has low range so it won't affect vayne most of the times
ONLY THE PASSIVE counters her while the active will be pretty hard to use against her but usually people who buy this item are guys like
who gets already shitted on by her and when she gets a kill she become unstoppable while you'll be fucked cause you can't run from her in dangerous situation so is pretty hard to not feed her ,Even if riot thinks she has clear strengths and weakness(which i think she has not) that doesn't make her immune to nerfs
TY FOR READ HOPE YOU APPRECIATE THIS AND REMEMBER TO UPVOTE PLEASE
