From my point of view, LFR is just no fun. It is one of those loveless implemented components the devs add if they do not want to add it. Based on a development bias.
25 foreigners get thrown into a matchmade group to play mechanics made for premade choreographed groups, just to show them the art and the final story. While the gameplay itself does not change from heroic or normal implementaion, the numbers are watered down. The people who get thrown into LFR are being put into content that was never designed for them, including the lazy implementation of LFR itself.
I would wish the developers would put more effort into the version of raiding content that reaches most of their customers, and would present a gameplay experience whch is worth playing. If i could give an advice, i would keep LFR in the game, just because it is massively popular, and add a solo mode to raids or dungeons (or even better a flex 1-x solution) to allow people to bypass the pain of having to group up with strangers, which is both no compelling gameplay and creates skyrocketed queue times based on the fact you need tanks and healers.
Beside the impression LFR is complete unfun, the rewards are also not worth playing LFR anymore. If world quests give an ongoing character progression, the lowest difficulty of the raiding content should as well.
