Knowing SE, they'd botch the coding and the NPCs would end up killing freelancers as well >_>
Personally, I'd take a more "fun" approach: If you get too close to the enemy spawn, you get teleported to a completely random spot on the map. The exact range of the TP zone changes within a certain parameter every 15-30 seconds and is not indicated.
As for premades, or more precisely, troublesome premades, well...I personally just boycott the queue while they're around and try some other time. I got several games and content within this game that's more fun than dealing with them. All I ask of them is that they don't complain about long queues.
