So… I’m going to say you are trolling at this point.
The solution needed for an LFR group to succeed is for people to push the big shiny button on their screen. That’s pretty much it. If they can’t handle that simple mechanic, they don’t deserve to see the end of the raid. It takes more effort to view the ending on youtube than it does to push that one button, so it is possible that some people won’t ever see the ending.
