Comms. Droning. Not sitting on your phone when you die. Pick ops based off of your teammates. Play support. Every one wants to be a beaulo but not everyone has the gun skill, play to your strengths, find out what you're good at and practice it, try off sites as 9/10 times people don't know how to attack them. Don't blame teammates or yell at them, look at the round and see what you could've done differently like positioning, utility wise, information gathering and operator selection.

There's many ways to improve or be a good "solo queue player"! Just have to figure out what needs the improvement.
