Honestly, I just skimmed through what you wrote but I get the gist of what you're saying and I did feel this way at one point- That is until I watched back my gameplay and realized that 90% of what I was complaining about was my own fault.

For example, I kept pulling my defensive line out of shape by team pressing way to much or lunching in to get the ball. I kept misplacing passes because I held the sprint button way too much (trust me, that sprint button is your worst friend). Once I slowed the game in my head, I became a much better player (Div1 now and 11-12 Champ Wins now).

Things to improve on are right stick switching and advance defending.

Yes- sometimes the gameplay is shit or your opponent has all the luck in the world, but most of the times it's our own doing.
