[Dune] Why aren’t more traditional melee tactics used?

Why do fights seem to almost always fall into individual melees, why don’t soldiers use physical shields and weapons other than short blades?

It's extraordinarily difficult to maintain the sort of fine control you need over the business end of a longer weapon such as a sword or pike to penetrate enemy shields. Only short blades that effectively function as extensions of your arm are practical in that sense. As such, knives don't lend themselves well to the sort of tactics you'd see with historically conventional arms.

Physical shields are probably regarded as redundant.
