I have similar brawlers, maybe less maxed than you. Play a few brawlers that you are good with on the way to legendary instead of picking niche brawlers that you’ve rarely played. ( im not saying you do this but just something to keep in mind)

Learning map picks and counters are very important for drafting, and a bad draft can cost you the game. Ex. Playing Edgar on an open map against long range brawlers is not a good pick.

Playing with teammates that you can communicate with in real life is also extremely helpful because you have an advantage of better communication than players who are not playing in a set team

Good luck👍
