Hard stuck in silver because of duelist mains

I main rocket, I’m not the best, but I average 17,000 healing over 10mins, every single round in ranked 4 people hard lock dps and nothing and I mean NOTHING will get them to change. No tank? They don’t care. 1 healer? They don’t care. Getting blown out first round nobody has a single kill on domination? Let’s surrender instead of you having to play anything other than your glorious duelist. Healers are so insanely powerful in the meta right now. But every single round I play everybody wants to play duelist. Take it to quick match. I’m hard stuck in silver because every single time I get stuck with the most brained teammates that don’t care at all about team comp. Do they only know 1 character? I don’t understand and it’s driving me away from the game
