For your Warrior stats, you should focus on Endurance, Strength and Dexterity.
Firstly, Endurance governs the maximum health of your warrior. As you may understand, this is the best stat to focus on when building a Tank Warrior. This stat is also useful for a Damage Dealing type of warrior, but for other reasons such as PVP Survivability and Solo runs.
Dexterity is also very useful for tanks because of the bonus it gives to Dodge and Parry abilities. The Damage Dealing Warrior will find Dexterity useful because of it's bonus to the chance of dealing critical damage as well as the Parrying bonus. However, if you play a DPS Warrior, it is more important to focus in strength than dexterity, here's why.
Without any doubts, Strength is the best and more important stat for any warrior. Investment in this stat improves your critical hit chances as well as the power of your attacks. In short, it directly increases your Damage Per Second. This is why Damage Dealing warrior will want to focus primarily on the Strength stat and then consider Endurance as second important stat. On the other side, the Tank Warrior will need to foxus on Endurance and then spend points to increase Strength. Any leftovers points should go in Dexterity, but remember, your warrior never have enough Strength.
