Umm ok I have already beaten him 3 times legit with 2 different teams. Its easy if u know where to take out the swordbearer for max dmg against Crota per run. We clear a wave of boomers then we unload on crota whe, swordbearer is almost down. The person who is going to use the sword needs to have a decent launcher to finish swordbearer off grab sword jump on rock jump to crota and smack the crap out him
