These structures maybe too big for small maps and not appear in every map. The current meta had created a norm for people base rush and the map diversity is kind of low like pipeline, guard duty and seamist become a filler map during off line and the repeatedly appear during active hours, so maybe can create bigger maps with game time become 1 hour instead of 30 minutes can make things more diverse.
The way interim apex works with sometimes is just very long like more than 2 hours is kind of crazy as you are not playing as a commander rather then the foot solider on the field so is kind of not helpful in making people during busy weekdays and for the experience in general.
