I don't either. But I can see the appeal of it. That's a 2 way street. If they want to farm engrams by killing every damn dreg. Then get a couple of sloth buddies and go nuts. Otherwise, if they die and move you forward. Accept it, go back, or leave the strike. All three of those are acceptable. But understand I don't like giving rewards to randoms, and if I get to the final boss, I'd just keep wiping us until the guy leaves, or catches up. Which probably wouldn't take long.
