Basically what the title says. Nothing is more frustrating than seeing a huge chunk of your progress disappear. Especially if you HATE doing the activity. It's bull crap, lazy padding to extend play. If you REALLY want to extend the grind keep it FIXED but a bit longer. This only punishes average players. Hyper competitive sweats will have no problem breezing through, but average players (the crucible step for Last word for instance) will be disproportionately punished. It is poorly designed. Have the step be, kill 150 players, or something. It is even, fair and not going to punish average to lower skill players by taking away progress. Or put a cap on total loss per match.
