Firstly, they look just awful. Nothing more pleasing to the eye than a 2" gap between frame and body. Second, it causes problems with important things like the fuel filler neck, brake lines, fan shroud, steering, wiring and several other things. Third, it makes shifting very difficult as it lowers the shifter and gives the shifter less room to move. Fourth, there is absolutely no reason to do a body lift any more than 1 1/4" and that is only needed for some mods like a tummy tuck, which will put the shifter back in the right place anyways. Finally, lift (outside of the exemption listed above) should only be achieved with a well laid out suspension lift.
