You shouldn't lose more points than you just gained from your last few matches combined. I played 3 games, and gained about 100 points max. I just lost 1 game and I lost 136 points. I'm further back because I'm getting penalized for teammates who don't have game sense. Bungie, please work on this. It's more aggravating than anything to be penalized and have your work from an hour, be gone, with it not being your fault.
