Don't see how its wrong to speed run strikes... you're basically doing the same as the OP and telling others how to play. Best way to not complain is to make a fireteam with only your friends. Playing with randoms will net you random games. I would love to see this strategy work on Nightfall or Heroic where you die trying to kill everything with no one there to revive you. Strikes are done best when your team is with you, whether that's speed run or killing everything.
