When i'm speaking of the netcode I'm not only talking about getting rollbacked, even passively the netcode affects how you play due to lag compensation, combined with the game hit box it makes like the picture I posted above happen. Even at three bars connection on 1v1 I might not get roll backed but I on a coin toss I can spike someone above me when my hitbox is supposed to hit downwards, because the hitboxes don't match up with their visualization. The netcode still needs improve along with other issues but i'd say netcode more due to me pretty much being forced to play against console wifi's.
