I always thought different beacon types would be nice.
A personal beacon
Similar to what we have now but maybe add some progression to it and better permissions.
A mall beacon
That would allow you to set permissions similar to a sovereign. It could have its own progression that increases its size which could be based on something like footfall or shop sales etc.
A guild beacon
Which allows for guilds to have an area together and some form of progression on this beacon also to allow it to expand.
