If the enemy team has something like Vi Yasuo, the point where Vayne is unkillable never comes unless you build tanky enough to survive the initial burst. In this case a Guardian angel wouldn't exactly help unless it's a one teamfight to win the game situation, and you'll probably want defense against that before your sixth item anyway, because otherwise you'll be made useless.

Four damage items and a Banshee's with a Randuin's isn't the highest damage build, but it's one that I've personally used to great effect. Vayne does damage no matter what, it's more important to be able to get off that damage than to have more damage that you never actually get to use.
