Here is the idea which should be developed by Inno:
The number of emissaries we earn should be reduced but the benefits they provide improved. Right now emissaries are very weak and useless except for one which give +1 fp.... We need something very unique for the emissary which provides +1 unit I think. It would be nice if they provided us with a special unit ( A General or commander unit which would be good for any era) . A unit which you don’t fight with but can place in a sector in GvG in order to improve defence bonus of that sector. Those special generals or commanders wouldn’t overflow the game because emissaries would provide only 1 per day per player.. I think this would make GvG more dynamic and interesting
Or a unit which would make your fighting army stronger. A leader some sort but not crappy “leaders” like Drummers or Color Guards. Unit which would be worth replacing one of our VF units with. Anyway, I think you got the idea.
