Still getting packet loss

As the title states im still getting packet loss issues even though i set matchmaking to local. 30-40 ping every game but still rubber band. Been having issues since February and i dont have network problems in any other game. Idk hows its been a year and it sti hasnt been fixed. 343 can add everything they want to the game but if packet loss and other server issues are still a thing, then whats the point of having all this content if the game js unplayable.
