advice on duelist main while solo queuing?

hey all! peak plat 2 but back down in gold lobbies and feel like i’ve lost my touch a bit so could use some advice for climbing:

i usually main reyna since shes self-sufficient for heals and blinds and im usually solo-queuing or with 1 or 2 others, but i feel like its teaching me bad IQ habits like ego-challenging dumb fights that i wouldn’t win in higher elo lobbies. my headshot percentage is pretty good and im good at thinking about where the enemies are without solid intel, so duelist role is definitely my most comfortable, but would you suggest i try and get good at a different role or duelist? if duelist is taken i usually try and play clove since she’s kind of a controller/duelist hybrid, but just feel like this isn’t a good long term habit (agent pick wise). any advice is appreciated, im in the trenches!
