Best advice I can give is this:
Don't try to play inquisitor like a warrior. He's still a spellcaster.
Don't try to use a staff with a warriors mindset. You're still a spellcaster
Edit: Changed to reflect what I actually meant
Maybe once the devs fix the staff + warfare synergy it might work but since half the skills have physical throws you're kinda shooting yourself in the foot trying to go melee.
The advantage if going a staff atm is simply that it has a higher base damage. This means that any skill that scales off of weapon damage is going to have a significant damage increase over 1 or 2 wands.
That said, dual wielding wands does significant damage on auto attacks if you have the right combos so I'm really not sure it's worth it.
Hope this helps
