I agree with all of your suggestions, I do know they said board wear and tear is supposed to be coming but due to them not showing us a roadmap anymore we are all being left in the dark.
to me your suggestion about movement and trick landings is the most important one. the character movement being too stiff is such an eye sore because our upper body and legs move in tandem which is not how we move on skateboards in real life because the vast majority of the movement especially turning is with our hips and legs and then our upper body follows, this is particularly noticeable with micro adjustments when steering left or right and going over sharp terrain changes resulting in our whole body snapping around rather than our legs absorbing those changes.
currently landing tricks does not feel satisfying because our characters feel weightless and when we feel weightless it removes that satisfying impact of hitting the ground and rolling away, it also doesn't help that landing if FAR too forgiving, even with auto revert off you can land completely off center or land directly on stairs and still somehow roll away which removes that satisfying feeling of landing tricks.
Another major contributor to that floaty weightlessness is the games auto detection system, when clearing a gap or ollieng over an obstacle big or small the game tries to hold your hand by lifting you up and over the obstacle and it's that extra lift and pull forward that creates that floaty sensation. this auto detect hand holding system NEEDS to be something we can turn on or off because it removes all sense of accomplishment and that rewarding sensation when finally clearing that stair set or gap, nothing feels good when it's handed to us and this system has been turned up a notch with every single season.
