At the bridge checkpoint in the Crota's End raid, there are six large podiums all spread around the abyss below the bridge, a couple of which are only reachable by using the swords air slash attack to drag the player further. Now, what I'm thinking is that since there's SIX podiums and SIX players per fireteam, it makes sense to me for something to happen given each podium is occupied by a separate guardian on each. If anyone has any thoughts on this or has already tried it themselves, let me know below!
