I see a problem with nations having multiple leaders. You talk to one and think you have a deal yet you don't because they have to run it pass the other leaders. People are assuming a deal has been made when one hasn't and now confusion is amongst us.
Another problem is people taking revenge a set later and not just having a clear slate. The LoR/DaK issue has been going on for at least 3 sets now and doesn't seem like it will end. One of the nations gets destroyed and then can't get back on its feet because the second a restart leaves protection it's killed. LoR experienced it last set and DaK is this set. This will drive players away and kill the game.
A solution for all these alliance/nap problems will simply be to post it in forums and sign off with the entire community to see. These will be formal agreements and not hear say. With this we will know if someone broke a treaty or not.
I suggest a conference should be done amongst all the nation leaders to discuss this and try and squash all the hatetred amongst them. Put your pride aside and think of the game. At this rate, the game will die within a year in my estimate. I'm getting tired of the constant warring that is over nothing and the constant killing of restarts, makes the game unfun.
War is an ugly thing, but not the ugliest of things.
The decayed and degraded state of moral and patriotic feeling which thinks that nothing is worth war is much worse. The person who has nothing for which he is willing to fight, nothing which is more important than his own personal safety, is a miserable creature, and has no chance of being free unless made or kept so by the exertions of better men than himself.
