Guild housing tied into GvG
Yup. I suggested the same thing in the housing thread.
Guild Structures should all have some base design that’s public for others to see that they all share. The private portion that only the guild can use and the external appearance are areas the guild would improve. Players would get an instanced room to decorate on their own and this room is moved from guild to guild or to the home instances’ inn if you’re unguilded.
The public portion of the guild structure could resemble the basic 2 forts map in Team Fortress. The goal is to break into the opposing team’s fortress and steal some top secret siege blue prints. When 2 guilds go to battle, their keep is simply imported to one end of the map and ANet can do a basic 1v1 2forts style, or expand this to XvX guilds. etc etc.
Since the public portion of the guild structures are common, it’s easy to have a balanced map. Private areas would be behind instanced doors that only guildies can use when not at war etc.
