Doing Crota normal last night. Final checkpoint my teamates realise they need a swordsman. I offer to drop out for a friend who should've been part of the original party. Someone else who was in the party chat but not playing offered to do the Nightfall with me. I'd already done it an hour or so ago and got a purple fusion rifle ( sharded ), so I switched to my warlock and ran it again. Got my second Ghorn. I also got my first in a Nightfall ( Hellmouth ) a month ago. As much as I loved getting it, I always feel bad for my teammates when it drops if they don't already have it themselves.
