Problem: Every emissary gains a benefit for reaching grade 5 except guilds/sovereigns. Guuls have a lower multiple bonus. You're visible on the map. And you get no emissary voyage. There is no incentive to sail around with that grade 5. All the risk of a reaper 5 with none of the benefit. It's far better to sell, lower, and reraise.
Solution 1: Allow guild 5's to claim an emissary voyage for the faction of their choice. One single emissary voyage, once claimed blocks claiming one for a different faction.
Or
Solution 2: Make a sovereign emissary "medley" style voyage that integrates the three factions in a single voyage. Not unlike an athena voyage, but smaller in scope and effort and without the second chapter.
Give guild emissaries a reason to keep that flag up and get a big payday for it if they succeed.
