Great tip, Buba, I didn't know the item would transfer when hot swapping. That makes it a lot easier. Though frankly, when playing solo it's rare for it to be very difficult to get to both objectives and bring them back. In coop it can be almost impossible, depending on which map you're on and the spawn locations, even if all players are going for them.
What really aggravates me about this mission in solo play is that it deprives me of an entire wave of vanguishes, and the same for checkpoint race.
