Apologies if there has been a thread on this already, but I couldn't find it. I really loved the /autogroup functionality during the event. I would totally use it in addition to manually searching around for a group, kind of like the lfg finder from back in the day. If you're sitting in the relic town and your toon has /autogroup turned on, you would automatically get placed into a group. The group leader can set /autogroup 4 for example to limit the group size to 4 if they wanna keep it small. As simple as that. If you wanna make it more obvious than an obscure slash command then add an npc named 'Matchmaker' to the relic town that has a dialogue where you can turn on your autogroup flag by clicking (and then the dialogue can explain the /autogroup command as well). I wouldn't add any functionality for limiting classes etc because the element of autogroup I liked a lot is the random aspect of it.
