Things to consider:
Kill the ogers as fast as possible or the orbs will be too far apart to detonate all at once.
The "no knight" strategy cannot be used
Same runner can be used for every rotation
People can die
If a knight gets away and eats some bombs you can still recover-just survive another rotation of ogres to get more bombs
Good luck Gaurdians
Loot has been confirmed to be he raid helmet and a primary at 320 light. You will also get a ship and a pretty cool emblem.
