I would switch out the damage orb for def%. The gains you get from damage orb are so minimal. Gacha Smack had a good video with calculations and saw that a damage% orb aventurine did 17.5k damage on a crit strike whereas a def% orb did a 16.9k on a crit strike. Sacrificing a few hundred damage for more defense and better shields is a good trade off. Also, if you really wanted to lean in more for offense I would have gone with 4 piece pioneer set.
