there is alot of fake wars going on so in order to reduce the amount or just not let the kds who are in fake wars to enjoy the benefits like:
-25% Military Training Time
-75% Gains and Effectiveness for operations to and from other Kingdoms
Lower Mana & Stealth Consumption
just make a minimum hits and Hostilities ops per day during all war long
something like:
10 hits on either side per day (have to be successful hits)
20 ops on either side per day (have to be hostile ops)
if both side are not in a fake war but just inactives/noobs kds then they wont enjoy the war benefits as well!
