Best PVE Gear

The formula to rate gear:
* 5.57 crit rating = 1 dmg (with SW:D in rotation)
* 1 haste = 1 dmg (presuming ~1400 dmg)
* 10 spirit = 1.1 dmg (1 dmg without kings with imp DS)
* 80 int = 1 crit% = ~4.36 dmg (3.97 dmg without kings)
* 1 hit = 1.364 dmg (when not hit-capped)
* dmg + crit/5.57 + int*0.055 + spirit*0.11 + haste + sockets [+12 gems] + meta [MSD or ESD] = sub-total + hit*1.364 = total
