I would love to see player housing and guild housing added as well, but it's probably never going to happen. They have said several times it would essentially be a pain in the ass for them, and the last time they mentioned it, they pretty firmly said no. Now, as devs come in and out, and people stop subscribing, they may eventually decide to put them in, as a very, very last resort measure, but as they have said before they don't see the effort being worth it, I doubt they ever would.

They don't want your characters hiding in their houses. It makes the world empty.

I'm going to reiterate my suggestion of a surfboard mount being pulled by a herd of Murglesnout.

They could make it so you could only be in the guild house for 10-15 min on a 60 min CD or something like that. Your guild home would be like a second hearth. I don't think it would happen but it could be fun and actually get people out more, not less. I'd have a tough time making our home in Zangarmarsh or Booty Bay. Cause who doesn't like booty?

I wouldn't mind a phased or instanced Guild Hall. To prevent camping, they could just not have terribly useful NPCs there, no AH/bank/mailbox/hearth/repair. Maybe guild rewards vendor, if anything. But spaces to meet in would be cool, like a big meeting hall with a lecturn, or some chairs by a cozy fireplace, or a trophy room with visual indicators of guild achievements. Players would still need to head out to craft, visit AH, or listen in on Trade chat, of course, but might add a bit to guild community apart from just green text in the chat window.
