I was in a team with really good players, but they were bad at being a team. We were doing crotas end. After six hours we were at our probably 50th wipe at crota, but I didn't want to be the guy that left and made it so that they couldn't beat it. After a while, everybody left. I jumped in with another team for maybe 20 minutes at crota, and we beat it. My reward for trying to be a good friendly guardian? 2 radiant shards... That's it.
