Y'know what's neat? Hardly any of what you just said is true. Cool huh?
LFR is a matchmaker-friendly form of raiding in WoW and it offers rewards at an item level lower than normal mode raiding. In Legion the loot tables were actually completely different from normal and above raiding. Actually, every endgame activity rewards better stuff than LFR. So best rewards for no effort? No. Some rewards for doing content? Yes.
And LFR isn't for people who "struggled with the game." It's for people who don't or can't raid with a regular group so they can at least see the inside of the zone and meet some of the bosses and finish the game's story. Helps for gearing up alts too.
tl;dr: get over yourself.
