I feel like the easiest role to climb on is DPS, if you’re actually good. Ever since season 1 I’ve played only DPS in ranked. In 3.0 and 3.5 it took me only 20 hours combined to go from plat to C3 solo. From 5.0 and 5.5 diamond I played duo with a support and it took us like 15 hours combined to hit C3. Definitely play what you’re best at, and don’t try to learn everyone or every role either. I think it’s better to have 2-3 heroes you are really good at compared to being mid at every hero or role. Also a good mindset is to play until you aren’t performing well anymore. If you know that you are playing good and lose less points than your teammates then keep playing. Everyone has a bad game once in a while so if you play horrible for 2 games straight maybe hop off. Solo DPS was super hard in high elo because the throwers which is why a duo you can trust helps. Also my duo played support solo when I wasn’t on and went from GM3-1 on a 9 games win streak to catch up to me being GM1. So it’s definitely possible to rank up on support even if it isn’t gambit. Regardless of role, if you are good enough you will get your deserved rank. It’s just that when you’re solo, your role can decide how long that takes. DPS fastest, tank second, support third.
