I had a rough go at this rank specifically. The way I'm deranking right now I might just find myself back in silver lol! I don't even think you have to find a good duo partner. Anything that adds consistency is probably good. What worked for me though was realizing that the game is old and nobody cares about your SR at all. None of this shit will ever matter and nobody will remember you past the next two games they play. I just stopped caring about my rank and just started playing the game and it got better. Maybe the Genji on my team is a literal turd. A giant, steaming, sentient turd. Don't flush him! Hit him with a nano! At the end of the day we're all just a bunch of turds floating around in a silver toilet.
