So in your opinion hiding in a room poking your head out to pop shot a boss is a far worse tactic than hiding in a hallway doing the same? Just play the game the way you want to. Unless you are willing to pay for anyone elses account then you really have no input on how they play. As long as the job gets done it doesnt matter. If you dont like being forced to run with randoms then make more friends so you can all adopt similar play styles.
