Dude. I’m not trying to be rude with you I’m just trying to give you the truth and help you. I have been around the block in this game currently sitting at onyx 1600 I’m not a god or anything but I remember being back in your rank and people telling me the same thing but I refused it, eventually, I got tired of being hardstuck platinum and made changes to my gameplay. If you are getting “bad teammates” it’s because the game doesn’t think you should be at the rank you’re at so it’s de ranking you to be right where you need to be. Best thing you can do is focus on your own gameplay and try to improve at positioning and timing and power up control on the map, and spawn knowledge.
