[Warcraft] If the Burning Legion is technologically advanced enough to have spaceships and giant robots, why do their foot soldiers (Wrathguards etc.) still use swords and axes?

They are just as effective as giant lasers, cannons, and other weapons.  We see a world where a mage can burn people with fire or ice.  Or even just use arcane energy.  You have a world where the maddening pull of the shadows or the nihilistic nightmare of the void can drag a person apart, albeit very slowly.

Your answer lies in the elemental energies that are present in the universe of Warcraft.  Living creatures of that universe are just more hardy and hale than real world equivalents.  A large sword, an ax, an eye laser, or a ship mounted cannon all do about equal amounts of damage.
