Then the mechanisms should be updated - for example, the war protection against outside hits only stands for hits from kds which wasn't targeted in last 24 hours by the kd in that fake/regular war. This rule could utilize the relationship meter - if kd in a war made more hits (relationship points) than the kd which was 'hit and run' then no protection, otherwise protection stands.
And to make sure that theres a hits in a "fake war" - protection against from outside hits is on only if both warring kds have atleast hostile relationships to each other. And if theres no hostile to each other then the kd page could show fake war instead of war.
My blood boils that theres interference of devs in middle of the action because ppl find out a way to use game mechanism in their advantage.
Its like changing rules of icehockey (eg golie cant be changed for a 6th player) or any other game rule in middle of game. Most likely there wasnt rule about golie - there was only rule about changing a player for a player, and then someone thought about changing extra player for golie. The rules (mechanism) allowed it.
Dont get me wrong, - i like clean fights, honourable play, i want that everyone can have fun - i like to win wars, but i dont like to destroy enemies so they wouldnt ever want war again. But this time i think its devs responsibility to make changes in mechanism if they dont want to see fake wars. (i personally think - that fake wars are not the end of world - it gives an unexpected edge to utopia).
