@Riot, What about changing Vayne's E to skillshot instead?
Vayne is strong and doesn't suffer from a weak early game atm. Making it to skillshot with decent/predictable projectile speed would allow some counter-play and she wouldn't just faceroll in the laning phase. Or just simply press it and get away.
who can stay at 650 range and poke,
who can farm with Q extremely safely or
who just rapes anyone in the game.
