Anyone else get these crazy negative streaks?

Assuming this is Control: No.

I mean, I do have occasional loss streaks that look like this ignoring KD, but I never have loss streaks that look like this while I simultaneously have such a high average KD across the games.

Most people in the subreddit won't say this because there's a culture of preferring high personal stats over winning in Destiny 2 and then blaming all the problems you have on teammates and lobby balancing but with such high KD/low win-rate streaks you are for sure playing Control badly from an objectives standpoint and contributing to your team's losses.

You are free to play the game however you like and free to ignore what I'm saying and be happy with your personal stats, but there's no way your KD is that high and you aren't winning more of those games unless you are part of the problem.

My DTR since people often ask for this to compare e-peens when I bring stuff like this up:

68.3% win-rate in Control with a 1.62 KD. I could have a MUCH higher KD, but I choose to win and play to win and that requires being aggressive on zones if nobody else on your team is doing it.

As a solo player its difficult to have a huge impact on the outcome of games in fully non-objective modes (notice my much lower 53% win-rate in Clash), but in Control if you aren't winning at least 60% of your games that's on you and your refusal to learn how to play the objective, IMO.
