I'm going to have to politely disagree with the OP on this one. You can grind and farm in patrol mode by yourself, Strikes take long enough without waiting for people who are still a mile behind fighting silly leftover enemies that don't matter. Sorry but if I'm trying get a few strikes done before bed and you are still farting about cleaning up a couple of leftovers rather than proceeding to the boss and the rewards, it's actually you wasting my time, not the other way round. First thing I do is hop on my Sparrow and get on with it, I make no apologies for that.
