There is a fair amount of strategy in terms of setting up shots, passing, and aerial skills. As already said, it comes into play more when playing with other people.
Not entirely sure what a "random physic turbo smash fest" is, and I can't say I've experienced any random physics that leave me hoping the ball mysteriously finds the goal. Have any videos to show?
Also, can you explain how you envision set plays working in Rocket League? Or "controlled passing"?
