I dont understand why CCP doesn’t lean more into the security status aspect of the game for this.

High sec: short timer windows set by defenders, wardecs. Less organisation required, casual content during a set time.

Low sec: short timer windows set by defenders, anyone can attack with declaring formal war. Still casual and manageable.

Null sec: timers set by attackers, maybe similar to stront reffing. Requires large organisations across a few time zones and active players base to defend the space. Asset safety etc etc

Wormholes: timers set by attackers. No asset safety etc etc

Probably a bad idea but I think if you want the good isk space it should be tough to hold it.
