Looking for Group upgrades
If you weren't aware,
the Looking for Group tool was in the original Burning Crusade. It wasn't as fleshed out as the "Dungeon Finder" tool in modern WoW, but it was definitely there to allow for groups to form for dungeons
and raids. Blizzard touched on this topic, explaining that they would be considering an update to this interface, "modernizing" it and making it a more functional tool, but
not allowing for automated group formation.
