Honestly don't think this would solve anything. Working with other players is just as much a part of raids as anything. Just because a player can beat 1 solo instance the way the guy on YouTube did (Yep, there will be a guide on exactly how to beat these that tells the player exactly what to do) doesn't change bad players in raids. They will only have to beat this instance once. Too easy in a game where most fights are based on memorizing boss patterns.
