I was late on the raiding scene. Like really late. All of the major cheeses were known of and patched by the time I started raiding (for both raids). That being said, my first time through the Vault, my team wiped to do oracles/Templar from the top. My first time doing Crota, my team cheesed the bridge. In both instances I had no idea what they were doing, so I just followed along.
