Indeed, a trend I've started to notice is the attempt to bring realms together via guilds in order to increase the pool in which players can communicate (Sanguis Astroism, although a religion, also can work in this way).
If we could have vassal realms, resulting in the creation of multi-realm empires, a message option to "all members of the empire" could help counter the shrinking player/realm ratio to stimulate interaction.
Well, yes, unfortunately the idea would then require a message-system reworking. If you can message members of the empire in the same way as realm-mates the feature would lose its
raison d'être, changing very little.
Perhaps if you could only message
all of the empire members but not individual members of other realms in the empire, unless you have their contact.
