That's exactly the point! In reality all we are losing is the fact that we know the base runner is trying to snag an extra base. Fundamentally, whether it's a relay or a straight throw to the base, this is predetermined by the outfield shift, depth,etc...
I want this indication back because if a batter hits a flare and decides to stretch it to double I can see that they are stretching it VS. I need this indication to know what is already known the ball goes to the second base not the cut off man. This same example can apply to several situations when we think about it! This game is impossibly unplayable because of this issue, IMO.
