Can someone please explain the weight system?

I was under the presumption that not adding certain supply points to your loadout would make you faster, more agile or able to draw your weapon much quicker but it doesn't seem to be the case. Even in more extreme tests I've tried to completely strip down to nothing but a pistol and no accessories or grenades but the entire experience was rife with people who were wearing heavy armor/ backpacks with LMGs drawing quicker than I did my pistol, every other character class being able to run just as fast as me, enemies being able to hear my footsteps just as prominently as heavier clases, and basically gaining zero advantage. So I guess the question I have is. Why ever choose not to have full equipment? Why not completely load up your character and why is this a feature? Why have the option to have less ammo or less powerful weapons if there's no class or playstyle variety to gain from it? Seems like the devs didn't think this one through at all unless there's something I'm missing here..

weight affects:
running speed
ADS time
and recoil (idk about this one just heard it thrown around in discussions)

low weight makes you run faster and ads faster
higher weight apparently lessens recoil
