My opinion is that it could be changed a little, but should definitely not be entirely removed. I personally have never seen this be abused, but I know that it is unbalanced. I was thinking possible balances could go along the lines of having it take a few seconds to aim at a target, and you would have to stand still to do this, and possibly have it be so you can only aim at a stationary target while standing still. I personally think being able to aim at a target is a decent idea, but not like how it is currently implemented, I think it should NOT be a viable option in normal combat or chasing someone down.
