I’d like LFD/RDF in WotLK solely for conveniance and maybe that’s why it’s bad.
People say LFD is bad because it makes the game less social and I can see why they’re saying that. If LFD were in WotLK you’d essentially be on a conveyor belt, getting slotted into groups, teleported to the dungeon, and once you’re done, repeat the process as many times as you want.
I’m sure that people will talk in dungeons regardless of LFD being in or not and I’m also sure that some groups would’ve formed without the use of LFD. What LFD does is remove the need to stare at your LFG channel and your LFG Bulletin Board until a dungeon you want shows up.
Quality of Life features while good for players, isn’t always good for a game.
People are different now.
