It's really cool that u see it from the perspective of a tracer cuz it helps me alot. However, also remember it's still a game, so I guess some physical constraints can be considered meaningless. I however like the idea of showing the player before start which moves he will miss with his current loadout configuration. I prefer that over the class system, because I really dont like classes.
I also see your point regarding the flips, but they just look that cool...
