How do i get access to old mechanics theories from legion and draenor?

Hey, I just discovered this website and after looking through mm hunter aimed shot mechanic theory, I was intrigued to find out how it used work with different spells and talents.

We don’t have the Legion version available anymore on the website, sorry. I can tell you how it used to work if you are curious. Our wiki was implemented with Legion, so I don’t know as much about WoD.
