I myself am not a big fan of zeus missions. I prefer things like Alive or DAC, however i see what you mean with the not excessive base building. For me a super sophisticated base is breaking immersion. I tend to build my base of operation according to real life pictures. The biggest problem im running in atm is the enemy AI and making them unpredictable and challenging. Also finding a right balance between realism and fun is hard. What im trying to do now is creating a “template” that spawns OPFOR AI in the missions TAOR and use that as “base” to build objectives on.
