WoW Classic – Warrior Stat Priority
Agility – Provides you with Critical Strike and Dodge chances, highly increasing both offensive and defensive capabilities of your character. If you get your hands on an “of the Monkey” or “of Agility” uncommon item, don’t be afraid to use it. Agility will be your primary stat at level 40+, as you will want high Critical Strike chance.
Strength – Your primary statistic that provides additional Attack Power and increases the strength of your attacks. Gear pieces that give both Agility and Stamina will be of great value to you.
Stamina – Improves your survivability by increasing your total Health pool. This is a very important statistic, but it shouldn’t be prioritized over more offensive Str and even Agi.
Spirit – Increases your out-of-combat Health regeneration rate, allowing you to minimize your downtimes. Do not underestimate Spirit, as it will be your primary statistic when under level 30 or so (this is because most of your Damage at lower levels comes from your Weapon, so Strength and Agility do not matter that much in the early game). At higher levels, it starts to lose some of its value and should be gradually dropped in favor of Strenght, Stamina, and Agility.
Intellect – This stat has close to zero value for a leveling Warrior, but… Intellect speeds up Weapon Skilling process, which means that Intellect Gear has some niche uses when a Weapon upgrade is of a different type than your current Weapon (you can put on Intellect Items when you are trying to raise your Weapon Skills quickly).
