We've all seen posts about the last mastery assignment for the semi-auto rifles.
DICE, you really need to take a look at this one. This cannot qualify as a challenge, getting 20 headshots in a round in objective areas requires only luck. Nothing else. With that said, this kind of challenge appears to be designed to stress people out and make them angry over not being able to complete it. I do not consider myself a bad player and I'm sure there are many out here who feel the same about themselves. Yet, we can all agree on this assignment not being fair at all.
