I do multiple bounties, and if I have say, 200 tears on mars, I would rather just get them done in the strike that I am doing, and not have to fly back. Also, I really only do roc when I get the strike without dieing or exotic bounties. Yesterday I did 5 straight for the exotic bounty, and lead my team in all but one in kills and got 3 legendary engrams and one for leveling up cryptarch. The guys I was playing with needlessly rushed, and died multiple times. I rushed with them, gave them a revive when convenient for me. The weekly comment was just a poke. If you feel that these strikes are too easy, and just want to skip all of it, so something harder. But you would probably skip that too.
