I feel like LFR used to at least serve a purpose which is now entirely gone. I mean mythic 0s give equal loot - take less time (and you get more loot per time invested), Emissaries and things like Warfronts are more lucrative. You don't get the raid quest in BFA anymore that some people completed in LFR to get loot, and at this point it arguably takes longer to clear all the LFR wings than it does to clear normal.
If anyone feels super passionate about LFR and does it weekly that's fine, but wouldn't you get more enjoyment out of doing normal instead?
