Mouthpieces and helmet fits

Why is there no option to wear gum guards correctly?? Also to adjust fit of your helmet back and forth to fit your head. Also sizes for helmets. There's no such thing as one size fits all. "Kids play this game and see oh that's cool you wear a guard like the pros do, Hanging out your mouth." Not everyone wears there gear incorrectly and frankly it's insulting to the fans who give so much and only ask quality in return. Not battlepass.
