Hey, after not playing the game for 2 years and coming back recently I found myself at the lower tier of player when I started. My first 2/3 weeks i was going negative in almost all my games. But, I quickly remembered the importance of team shotting, not peaking when your health is low, running away when necessary, and try your best to focus on headshots for the extra damage. Use your abilities to your advantage, an opening grenade/melee ability could help massively in certain situations Also if you’re on PC, try to plug in a controller and see how it feels compared to KBM. The auto aim could help you greatly. hope this helps a little, good luck!
