"Having enough cover around objectives to ensure safe spawning, trying to avoid endless spawn killing by the attacking faction."
Please keep in mind that your spawn system is a pain in the ass for both defender and attacker.
As an attacker there is so many time i've been shot while moving to objective because defender spawn like 2 meters on my back. This is realy stupid and unlikely possible, i mean its like you move strainght to objective, weapon up, with squad formation and "hop" def spawn 2meter behind like 2s after you pass by the place and kill all the squad.
So as a squad leader you have to put your long ranger shooter or light machine gun behind the spawn area...and ask him to do spawn kill until the objective is under 75 tickets (i mean he has to shoot everything in squad path or any spawn behind).
But, there is and other fact for witch my english skills have reach their limit but i'll try : i've seen player doing insane behevior such as moving in the objective area to turn on the alarm then run behind the spawn to do spawnkill. And they log in to do so the whole play time they have and do nothing else but this. (Darter is funny spectate tool). Nothing we can do about this, but please think about my first fact above.
I understand spawn system is a real dilemma for your mod but it realy need to be improved.
