The game has aim assist built in don't you understand that? They even said in previous interviews they wanted players to be able to do things they wouldn't think they'd be able to do, how else do you do that? The hit box is clearly very big I've found myself just mindlessly spraying with weapons on both PVE nd PVP and I'm miraculously getting critical hits, I'm no great player but I'm not blind enough to not notice that.
