So.. The PVP KNIGHT AMULET = Power Precision vitality???
While Knight ARMOR SET = Power Precision Toughness???
once you have played the game a while you learn that PvP changes the stats on certain gear.
I have a warrior in full knights weapons, Armor and jewlery and everything is Toughness primary and power, precision secondary. What you are seeing there is that in PvP Knights is one of the paths that got royally screwed.
PvP Knight amulet had toughness instead of vitality last month. This change is great for me, though, as I tend to play the squishier classes that benefit more from the vitality than the toughness. Knight's amulet with a berserker's jewel. Yesss.
