Yeah it looks a little silly with the improvised weapons from a ship wreck version but it's a 100% doable and has an awesome feel, it's like you managed to import an Xcom character with a pistol and shield into D:OS2 and are wrecking havoc with the new spells you learn at every possible moment.
I've yet to test how wand and shield interact with Oportunist talent but for when the game launches I will try and build a tank with wand and shield.
