So I should try to shoot for 20% Haste (at least), 20% Parry, and 25% Mastery? I have a ton of excess Mastery.
I'm going to try to replace the Versatility trinket with the Str/Crit trinket from Halls of Valor (Hunger of the Pack) and see where that brings me.
I also have an 860 Mastery/Versatility ring which blows everything else out of the water as far as ilevel and stamina. So it's the same case as my new neck (164 more stam than my old neck while dropping Haste, and my DPS neck has Crit/Haste as the same stamina as the other neck- both are 850).
