There is a lot to unpack here. What parts of the WoW Warrior are you trying to emulate?

Also watch out for trap options. If you go Dex based you're better off not wearing Heavy Armor as it has strength requirements. Also certain Barbarian abilities like extra damage from Rage and Reckless Attack won't work unless you are attacking with Strength.

Anyway a WoW warrior wears the heaviest armor possible and prioritizes strength and Stamina (Constitution).

Strength based Fighter 16, 10, 16, 8, 14, 8 is a tough, strong, perceptive warrior. Plate and Shield makes for great AC. Heavy Armor Master for great damage reduction. Dueling is a great fighting style. Think of your Superiority dice as your "Rage".
