There aren't enough pictures of dead horses, but I'll chime in nonetheless: LFD/LFR are tools, what matters is the content. If it's faceroll, nobody is going to say anything to anyone and just pretend anyone else is a bot. If it takes coordination and planning, some may play a different role, for example leading the group/raid, coordinating healers, cc, etc.
Most of the automated group stuff is facerollable, period. Tah dah, reason #1 why nobody fosters community in randomly formed groups.
There are some other reasons:
- Scarcity of certain roles, hence the need for multiserver matchmaking to speed up (theoretically) the queue times.
- Content made obsolete, for example WoW 5men dungeons that become speedruns for the few that still care doing them.
- Absolute lack of tools to list other people in a xrealm friends list: let's say I meet a great mage, good at dps and good at saving people from oh shit moments, too bad he's not on my server: chances I'll meet him again? 0.00001%. Real ID gets too personal sometimes.
- Content lasting 20 minutes tops, with very few exceptions: you are not embarking on an adventure with potential friends, you are just heading to the mall to do a quick purchase of goods (tokens, currency).
- No dropped loot worth talking about: funny enough I enjoy more the dungeon runs done during levelling because I often get nice upgrades that last me a couple levels.
- More to be added according to your personal experience and taste.
I'd be for a LFG tool similar to EQ one during PoP: it was used to list class/level and a line of notes where you could write what you were interested in.
I'd even be ok with no instant travel nor teleportation to the adventuring area, maybe do a McDungeon server for those who want those features and a Immersive server for those who don't want them (yeah I'm biased, I still play WoW tho).
------------------------------
I liked the EQ system. But i'm sure many many others didn't. You were in areas so long you knew most people your level and getting a group wasn't as hard as people make out. Send PM to group leader, get your name on a list and wait to be called in. Solo while you waited (if you could). Ok it wasn't the quickest way but it felt the most natural and immersive. Was also a good reason to join a guild make friends and be good at the game. but yeah if you don't want to wait or make friends be in a guild and be max level asap then the group finding tool is good.
Given that I've always been in a good guild during my EQ time, I rarely pugged, but when I had to, I didn't like the concept of lists at all and I certainly don't find them neither immersive nor natural. Natural would mean I talk to people while in town and we decide together to go hunt for something. "Frenzy got 1 free slot, next on list is...." doesn't sound very immersive to me, on the contrary.
