Well am gonna give you an example about the current ARs if your suggestion will be added, imagine i'm in TR or FFH for example which their hood near the oil factory and I play as criminal, I just die and keep respawning there means that doesn't matter how much cops there are, i'll keep spawning and killing each one of them and I found that unfair for others, you have the ability to teleport two times as you said and I think that's enough, during a criminal activity, making you able to respawn in your base as much as you want gives you the ability to rush on the other team and it doesn't matter if you kill or get killed so imma go negative here.
How about a script that only allows you to spawn or teleport in base more than twice if there isn't an active CE/AR around?
