Like the other guy said. Watch a video, or even read a article Yeah it may not be the best way to learn but u have a general idea. Alot of people don't want to explain the entire thing to multiple people, but if u go in and say hey I watched a video and everything. What positin you want me on, if ur a little worried just ask if they mind running it thru you real quick and explain you watched/read what to do and want to make sure u understand correctly Alot of people will take this as u making sure you don't screw it up and will give a quick explanation, those that give u issues are also likely the ones who wouldn't have let you finish the raid anyway so
