For those who would not know what I'm talking about: when you send a diplomat to improve relations with a country, you get a immediate small relations boost, in addition to the monthly tick. Which means if you send your diplomat on November 11 at the start of the campaign, you can recall them on December 1st and send them again on December 12. If you do this every month (losing one day each time), you can get to a +100 modifier roughly twice as fast (in game time, not real time obviously) as you normally would.



Why does this exist? This makes it so that often the best thing you can do (if you need good relations with a country as fast as possible, or simply it's the beginning of the game and you want everybody to start liking you), is extremely tedious, sending and recalling most of your diplomats twice a month.

If for game balance the devs want the inital relations boost when you send a diplomat, they could make it occur only if a diplomat was not improving relations on the last monthly tick. If for some reason they want human players to improve relations faster than the AI (since the AI doesn't do that), simply increase the rate at which human players increase relations.

But currently the game is made so that the correct way to play is unfun (on this aspect, I'm not claiming hte whole game is unfun), which is pretty bad game design...
