Vayne Tips?
I've been playing Vayne again recently, and I'm curious if anyone can give me some tips for her?
I've not done bad, and so far I've actually carried the three games I've played with her. Got a penta too :D
The thing I'm mainly concerned with is my build. It typically goes like this:

But then the game ends, usually.
After that, if it doesn't end, I usually try to get at least 80% crit, if not 100%.
Can anyone suggest 3 more items for me?
Or just tell me which of these I should build after?
or 
Then
or 
Finally
or 
The final build I would strive for is:

Is this good? It does give 100% crit, but it lacks the armor pen, which I'm fine to sacrifice since she does % true damage. Can anyone give me some different ideas? Or opinions?

. I know it seems odd but you can survive his burst with minimal damage to your build. A extra second or 2 of life gives you and your team time to react. I really hate zed. The second someone is out of position he can get through and dive you and get out clean killing you or low enough to back right before a team fight. Few champions can tilt a battle that easly but Safely without great team play is not ok. Sorry I really hate zed went on a rant.
for Zed ;-;
