Simple concept, decent enough execution.
You can kill enemies no matter how far away you are which makes things easy, but also kind of necessary since they notice you from far enough away that they converge on you pretty quickly so pre-emptive crowd control is too good a tactic to pass up.
One mechanic I don't like is dying if you're in front of the payload, it feels like too much of a punishment for something so simple. Even enemies literally trying to kill you deal less damage than a friendly unit you physically NEED to be close to at all times.
