I think some sort of revive system would make the game a bit more enjoyable. Yes, the developers have probably thought of this and left it out for a reason.
My first few games I really liked that the game punished you for dying, it made me work extra hard trying to stay alive, made the game feel more realistic. But now, a few more games later it's just gotten so annoying. Walking back after dying takes way too long because of the map sizes (Love the size, don't get me wrong), but I think implementing some sort of revive system would make a game a lot more enjoyable as well as speeding things up a bit.
Maybe a gadget like BFs defibrillators or Armas revive?
