I recently came back to MW3 and my KD has been dropping and I've started losing more too. It feels like the game and connection is way more slow and it always feels like I'm on a 3 bar. My drops-shots arent working and I've left 2 games today. Feels like I'm getting worse and worse. 2 days ago I decided to get a good KD game, So I camped my ass off in a dominion game and actually managed to get a MOAB. Near the end of the game I was 35-1. But I noticed we were losing so I had to run in and try to win. Game ended 43-6 and I didnt manage to win.

My KD Is currently at 2.76 (dropped from 2.90) and my W/L is at 3.3 (dropped from 4.0) I always play alone and I always play TDM (my TDM KD is 3.0)

Are there any fail-safe setups to use?

Anything I should try and think about?

Any overall tips?
