Dear developers, there is a detail that the Total war saga went unnoticed, and I think you can use it to your advantage. You see, when an ally has a territory, which is conquered by the enemy and then we reconquer it, nothing happens. What I mean is: we should not lower our relationship with our ally the fact of not giving them back the territory recovered. Our ally should wait for a return and in case of not doing it, we should lose relationship. That option would make the game more fun. However, I recommend that this option can be activated or discouraged, since there are many people who do not enjoy the true complexity. Greetings.
