Aim assist doesnt snap the sight, it slightly gravitates the sight to an enemy on close range in relation to YOUR movement but not the movement of the enemy. So if you aim straight forward and strafe past an enemy, your sight will automatically bend your aim towards the enemy, but it wont help you track the aim if the enemy moves and you dont. Its a big deal in close combat, "spray and pray" situations, especially with high DPS weapons like R99 etc.
Anyways, I still believe smurfs and high skilled players that havent played much ranked and got demoted down to low tiers (like gold and plat) are both the major cause of people getting melted and one-clipped. Its a poor ranked design and I guess Respawn designed it like this is probably because they get "fake" player count statistics when most players have 2-3 accounts.
