The strike itself is not the problem. Unfortunately, you were matched with players who loaded into the strike, but are farming kills outside of the strike area. This tends to be popular on certain strikes, that have starting points close to Lost Sectors, or simply start in enemy rich patrol areas. As some pinnacle/ritual weapons require kills within the strike playlist, players gravitate towards the easiest path to completing those tasks. If you find yourself in one of these Fireteams, your only option is to re-queue for a new activity, and hope to find a team that is actually wanting to play the strikes through as intended. You may even want to try forming a team ahead of time, to avoid being put into matchmaking.
