Spawn protection is two-sided. Players are protected from receiving damage, but also prevented from dealing it.
If I were to simply deactivate both of these, people would be able to shoot another player and immediately start damaging them without them being able to even react.
So you're saying only the protection should be disabled, but not the prevention?
So basically if someone enters an interior and immediately shoots someone, they still can't do any damage, but people could damage them? But then people will complain it's unfair that player A can do damage to player B but not vice-versa...
