There’s a new buff called Firebound that gives you increased Recovery and Super Regen when close to allies.
Also, when you kill the carriers they drop 3 balls that you barely have enough time to throw 2 let alone 3.
Seems like Bungie wants us to run together this year instead of sitting in a corner camping enemy spawns.
You can get all 3 as long as the wave spawns around the central area. Aim slightly above the bonfire and it should track to it when you throw.
