I suggest finding a brawler you really like to play and practice them until you can win easily at around 500ish, and then just push them up to 700 range. Rinse and repeat for other brawlers you like to play. If you dont enjoy playing a brawler, then dont play them. I literally havent played a single game with poco pam or piper(and a couple of others) since like january (when i got them 500)
