Zypern is too weak to survive alone. Currently, Zypern is making alliance with Vyseus. However, it is highly inconvenient and impracticable for Zypern players to team Vy before joining any fight. This may be one of the reasons why high lv players seldom join the wars (don't want to kill friends or be killed accidently).
It is suggested to have a national party team option fo include also a selected nation of your choice in addition to your own in the Gameplay menu.
Think it would encourage more Zypern players to return and play actively.
