Solo Queuing Sucks (bless I don’t have to)

It’s crazy how hard solo queuing is in ranked. I just started playing during szn 8.5. Couldn’t get out past silver 1. Got a duo to play with me and we made it to gold 2 but kept falling up and down. I genuinely thought I sucked. Started playing with a quad and holy just climbed up like it was nothing, keep getting MVP back to back. I thought I was the problem, just hit plat now and I can say if I was solo queuing I’d prob still be stuck in Silver.
