LFR isn't broken. LFR is pretty much the best thing to happen to the WoW community. As someone who used to do hardcore raids, I can say that LFR has completely and totally killed any desire that I have to be shackled to a raiding guild. Giving people content without guilds is bad for raiding guilds because they're no longer mandatory to have some sort of character progression, but it's great for the players because they don't have to deal with abusive guilds that attempt to force them to play X nights per week and guilt them when they can't show up.
