1) Remeld the helm to 18ACC/25CRT/18DET/18SS. This set-up is BiS
2) The chest piece is junk
3) You need to remeld your belt to be 19ACC/19CRT/12DET/18SS. This set-up is BiS
4) If you cannot get those melds, then you've wasted cash and they're junk.
5) You have too much accuracy. 535 is the accuracy cap for T13. T10 is 492 if i remember correctly.
6) Grind the shit out of WoD to get upgrades and Solds, yes. Get rid of that crafted gear if you cannot meld it.
7) Buy the i110 sold gloves, they're brilliant as you're over-capped on accuracy
