I've been thinking about the changes coming to LFR ever since yesterday's big post about raiding in Warlords. One of the things that seems really clear about the changes is that LFR is now seen as part of a progression path for raiding - at least some players are expected to go from LFR to normal raiding in the expansion. With the removal of shared set bonuses and even tier gear from LFR being entirely gone, LFR feels to a degree like it's being downshifted in difficulty and placed in a different position for player use than how it is currently employed. Right now, for many players, LFR is their raiding. They don't run flex or normal, much less heroic. And with dungeons basically only for valor farming, LFR has become an important part of people's endgame.
The idea of making LFR a stepping stone to normal raiding via the incoming group finder is interesting to me. Since you won't be able to get tier gear, or scaled down versions of the same loot as in normal/heroic/mythic, LFR feels like it will simultaneously have less and more importance. The effort to elevate dungeons to a much more prominent role in endgame (especially challenge modes, which will actually reward gear) and make it so players have an incentive to try and make the jump from LFR to normal/heroic raids. It's an interesting shift in priorities, but what will it mean for players who currently use LFR as their endgame?
