Warrior PvP Tauren 2H sword spc

Your Tauren warrior will benefit a lot from his passive racial: Endurance, which is +5% to his/her total health. However, it doesn't really impact the spec that you pick. I'd recommend you start with a 31/30/0 build (with improved swords). This is a very popular combination of fury & arms that gives you both Mortal Strike (great for burst damage and against targets receiving heals in arena) and Flurry (a great compliment to a high critical strike rating).

This is probably one of the most straight forward builds I can give you for PvPing with your warrior.
