Main priority is grab yourself 5 or10 ppl that you like to play with and do a premade, set your tactics and build on losses by improving said tactics. It immediately eliminates any problems regarding player discontent, because they all feel like they are contributing to what can be a "failproof" win.

otherwise if you feel that you are getting too much grief, you could run a two box, it will take twice as long, and your 2vx win rate will plummet but they can't blame you for a loss then will take longer to get all the marks tho, so i would suggest premades
