When you travel to your guildhall you are instantly directed to a new PVP map. Only on this map, it will only show your guilds hall. I propose they make the PVP map bigger so it can fit in all the halls of your alliances guilds.
To take it a bit farther, they could make it so each hall was in a spot on the map which represented the theme of their hall, such as 'Burning Isle' would be, of course, on a firey island. Course this might be hard to fit into 1 map especially for halls such as the Imperial one, but it's just a suggestion.
Guildhalls.

I see what you're going at, but I think having one island on the map as a Guild Hall is fine.
