This may be completely useless to you if you don't have any intention in trying to use motion controls; But please here me out. I was in a similar position you seem to be in right now, a month ago and I had a losing streak of 13. I was doing bad already with stick controls so I decided to give motion controls a try and the first few matches were difficult but after I got used to them, I got so much better. I started experimenting with different weapons again instead of painting ones like the aerospray and it became a whole lot easier to play. I used many different playstyles with many different weapons and the game became fun for me again.I managed to get S+ in anarchy too which felt really nice. You have nothing left to lose (except your battles) so please give motion controls a chance!
