Guild Hall

Sounds like it would open up a lot of exploits as players would have a lot of control over the data in that zone.

Still, the possibilities for fun would abound. Random changes in appearances for visitors. When someone exits the Guild Hall it will take you...where? Entrance fees and charges for entering the specially new and improved part of our Guild Hall.

It's a long line, but it'll be worth it! Honest.

So I could leave my guildhall and zone into TeamFortress2?

IIUC open instances cause less server lag than spinning up new instances.

I hadn't considered intergame zoning. Off to Zork!

Just sticky the guild teleport selection between instances

Ooo, host all housing zones as one big place. Sell spray paint, paint sticks and cleaning supplies.
Follow with a revamp of guild wars.

Players being able to exploit the code running on their machine to duplicate or remove items from players would be worth it?

I wasn't aware we were making serious suggestions. I will be more careful. Honest. Really, well maybe not always.

Not sure what the point of the suggestion is otherwise. Why bother adding noise to a thread?
