Guild Hall's
Wouldn’t be unreasonable for the Norn to provide guild halls and Asura to provide gate transfers.
I say those two because Sylvari and Charr likely have no cultural interest, and the humans of Kryta and Ascalon actually banned guilds from owning land after the Guild Wars, which is why the guild halls in GW1 were only on land owned by Cantha.
That said, I don’t think Anet has any interest in it, for whatever reason.
