Finally got our Flawless Raider Achievement... the best part about it is we did it post Templar patch. This was our 5th or 6th attempt and it's definitely a challenge. The farther you get, the more nervous you get because you don't want to be the one to mess it up (I was the fail on our very first attempt). Had a great team to run it with and got it done in under an hour. Video of our run (audio is crap but the video is decent).
