Well, real forcefield manipulation allows two feats which are freaking awesome.
1) Forcefield Inversion (that stunt I did in New Beginning 6, where the forcefield keeps YOU in, instead of keeping other stuff out)
2) Forcefield Bypass (somebody generating holes or tears in the forcefield/barrier of another)
