Currently, beiging is bad. If you want to win a war, u dont beige. Why? Because if you beige an opponent it rewards them with time to rebuild, restock, and regroup. They can exit beige at any time and declare a new war with no negative aspects.
My suggestion:
Change the beiging system, so that it becomes the focus to win a war without hurting the winners.
Instead of x amount of days without being attkd. Cap it to 12 turns of non attks, after which time the beiged nation can be attkd but cannot start any offensive wars until beige ends... And cap total beige time to 4 days which can be reset Everytime a nations res drops to zero.
So, recap....
4 days of beige when an opponent beats you, the beige cap can be reset Everytime your res drops to zero and your bank is looted. The first 12 turns you get a reprieve and cannot be attkd. The next following 3 days you cannot start offensive wars but can continue to be targeted with defensive wars.
