Another thing I would do is the following swap
- Hallowed Ground -> Chains of Oleron
- 1 Skyshard Powder -> 1 Arcanum Dust
This way your OA, DA, Elemental Res stay literally the same, you lose a very tiny bit of damage but you gain
- 6% Movement Speed
- 24% Trap res (of which you have none)
Note sure, so many good weapon/off-hand components
