So why does every on e add weight to the B4 and other buggies?

As mentioned, its all about balance really. Alot of cars these days have gone mid-motor to optimise weight distribution to suit the high grip tracks we run on in this country so when it comes to running some thing a bit old school like the B4 you find adding weight to front helps the balance and gives you half a chance of keeping up with the mid-motor cars. The B4 was designed when we were using heavier electronics/batteries so now with the lighter Lipo's and slimline servo's the weight bias has moved rearward. Thats why people either add brass front bulk heads and weights under the servo and/or Lipo to their B4's, to bring the weight balance forward again allowing the car to work as it was designed. Or they just do the C4.1 conversion bringing the motor forward.
