Are you winning those matches with like high k/d cause I find that I get more drops when I'm middle to top of the board. I tested that theory for a few matches and if your just barely trying you almost always get nothing even if your team wins. Could just be random drops too 🤷‍♂️ I've gotten like four engrams out of like 6 or 7 matches I just played and one of them dropped the new grenade launcher but I have already reset my rank twice so idk if that changes anything.
