My experience as a Final Fantasy XIV player is that Duty Finder (the equivalent of LFR) is such a massive necessity for quality-of-life that I'd never ever be able to go back to an MMO without it. I used to play EverQuest back in 1999-2000, and I ultimately left after a year or so because everything about that game was an exercise in frustration despite the cool concept. I didn't get back into MMOs until I discovered an MMO that actually respected the player's time and didn't require everyone to jump through hoops and sit around and wait for people to bite just so they can play the game.

And, mind you, Duty Finder in XIV isn't just a raid thing: every single piece of instanced content uses it, even levelling dungeons, and that applies whether you're queueing solo, queueing with a partial party, or entering content with a fully premade party (even right-clicking on a dungeon entrance just opens up Duty Finder). XIV doesn't just respect the player's time: the entire design of the game is built around respecting the player's time at a fundamental level.
