Are you on console? I've been getting much better this season and really enjoying it compared to the last few.

Do you use builder pro, if not you should.

Adjust your sensitivity, I slowed down my horizontal and vertical sense a little so I stop missing shots and can track better with my shotgun, then I upped my horizontal and vertical turning boost so I can still turn fast so I can build quick still.

That really helped me. Play more solo's. When I play squads I always play random fill, but it's very frustrating with all the good squads and getting shot from every direction, you'll get better playing solo's.

I've been getting better at editing myself, just play around with your settings in playground.

If you're sense is too fast or too slow you will not do well
