You could go several ways with this, depending on the situation you're in..
If you're botting with your main account, and you wish to continue leveling your Paragon with a Wizard, then try and stick with a wizard and upgrade things.. I strongly suggest getting alot more STR/ARMOR to give you more Damage reduction. As well as gaining more DPS would be a big improvement. What you've not stated is Life, This is most important as it'll help keep you alive longer (obviously) if you've got lower DR, However Life/DR go hand in hand.
That said, If you're using a seperate account, or that you're low level paragon and wish for a new class... I suggest Barbs, They're powerful, with great survivability.
I myself currently have a DH that runs Act 2 with good success. 80k DPS, 71k Life, 600 Allres, 5.3k Armor..
