Not really sure why we have people talking about moving on to other difficulties. That's not what LFR players do, that's not what LFR players are supposed to do. LFR IS their end-game. Whether you like it or not a fuckton of people cap out at LFR, and a bunch of people at Normal, and a bunch of people at Heroic, and then a very small percentage of players ever set foot into Mythic raids. The more casual the content the more people run it.
