I only stick to that with the hard raid. I don't want to be explaining base mechanics to someone for the first time just to be unable to revive them when they miss a step. Not worth the time. Walking into the normal raid with no experience is ok but not polite. The previous responses are correct, walkthroughs are all over YouTube. If you join a hard raid group without friends or a Sherpa and you don't know the fights the leader is justified in booting you.
