The biggest problem with lfr (imo of course) is that they made it necessary for real raiders to run it. It's a ridiculously easy encounter which should be set aside for ridiculously "challenged" players, and not something required for people who know not to stand in fire just to get their set bonus. Take the tier loot out, the ilvl is fine but make it all non set. That way the players that way outgear it aren't forced to deal with people who barely meet the reqs to get in, and vice-verse.
