I don't think it is a necessary change.
What is more important, in my opinion, is to bring back the differences between weapons classes and to add effective recoil and challenge back into the game.
We've gotten to a point where nearly every weapons class works the same. SMGs can be used across the map as effectively as an AR. ARs are effective in close range and can be as accurate as a Sniper across the map. LMG's are more effective for Sniping than Snipers are.... you see where I am going with this.
Make it so that every class works how they are intended, create maps that makes them all viable options. Make it so guns have noticeable recoil again so that skill and aim is brought back into the equation and reduce the effectiveness of hip fire... and I think you solve a lot of the issues.
In a Fast twitch shooter, you don't always have the time to adjust for bullet drop, etc.
