At 4:10 it talks about equipment called tactical insertion - "throw it down and it determines where your next spawn is - choose where to respawn".
That would be very useful indeed for jumping in public matches, because you could get to a certain point, throw that insertion down, and then if you get killed/fail the next jump, you will just respawn back where you were?
Im guessing there will be something to stop that like you can only use it a few times per match or something, but if not that will be pretty useful

Edit: Enemies can see the tactical insertion and blow it up so you don't respawn there, which is the "balance" for it as said on the video. Still sounds extremely good for doing jumps.
