I’ve hardly done an LFR this whole expansion on any character and as a result, I hardly ever think about them. I suggest you give that a try.
As far as loot goes, LFR used to be the first step for gearing up a fresh character. Blizzard have since added world quests, emissaries and finally warfronts which have undermined LFR loot.
If I can gear better without setting foot in a dungeon or raid, then LFR loot is below par.
