Guild Wars 2

This is not a topic about wanting Guild Halls, but rather what should be in the Guild Halls. Such as in GW1 there was very little to do in the Halls expect for 1v1 against friends and guildmates. It was extremely narrowed and was usually only used for 1v1 and quick access to merchants and special gear. What should be added to Guild Halls that would make them more exciting in GW2? Basically, what would you want to see in a Guild Hall?

I will try to keep a list of constructive ideas.

1. PvP 1v1 and Within guild TvT.

No one has anything they want in the guild halls?
