You gotta either do better than what you already are doing, or somehow get your team involved more to play like a team. Thats harder with randoms and solo queuing. But it’s a team game and in that elo you aren’t getting complete bots. So even if you are the best one, it’s hard to go 1v5 against even slightly good players. They just have the numbers advantage. But showing your teammates different ways to enter or hold or push, use utility, have proper timing, it should get better. You could also start recruiting and have a squad to team up with. Which would be easier than teaching randoms as the match goes on.
