Warriors appear in Final Fantasy XI as one of the base classes available to a player from character creation. Warrior is a well balanced job combining both offensive and defensive abilities. They have no MP but a good amount of HP.
Since Warrior is a basic job in Final Fantasy XI, players can choose to become a warrior at any time, including when starting the game. A player who chooses to become a warrior when creating his character will be given an onion sword in addition to the adventurer certificate and ring associated with each city for qualifying races. Also, preferred races for this class are the Elvaan (because of their superior strength) and the Galka (because of their high HP and Vitality).

Combat Skill Ratings
Warriors in Final Fantasy XI
The role of warriors can change over time. In the lower levels, Warriors are often expected to tank enemy creatures, but as the game progresses, other jobs become better at this job. Warriors become primarily offensive in nature or become a "First Provoke" class. At any level, a warrior is a useful ally though. They can use most weapons and have a good rating in many of them. They excel with the use of Axes and Great Axes.
Ninja is the most common subjob for warriors after level 20. The ability to Dual Wield is highly valued. Most Warriors will wield two axes, allowing them to do great damage and gain TP quickly. Utsusemi is helpful to avoid physical attacks when the Warrior gains the greatest enmity after a weapon skill or in case they need to provoke to save other party members.
Samurai is a viable subjob for Warriors who want to use great axe, great sword, or polearm at high levels. Samurai both helps the warrior gain TP quickly through its store TP trait and meditate, but it also provides the ability hasso which gives haste, accuracy, and a strength boost to users using a two handed weapon.
Monk probably remains the most popular subjob for warriors under level 20 and will occasionally be seen as a subjob for even higher level warriors. Monk statistics compliment warriors well and provide a moderate boost in total HP. Also, some monk abilities are useful for warriors, like boost. Martial Arts reduces the delay of hand-to-hand attacks for warriors wanting to skill up that weapon or who want to actually use this type of weapon, though such use is rare. With hand-to-hand's delay being one of the lowest, you hit more often. Though doing less damage you are more likely to cause more damage than say, a warrior. When a monk misses one hit it's no big deal as he'll be hitting again real soon. Unlike the warrior who if he misses, you have to wait a while to try again.
Thief is a great subjob upon reaching level 30 and obtaining Sneak Attack. Sneak Attack gives a free critical hit that with 100% accuracy, which makes it a good choice for combining with a high powered weapon skill. Also the Thief statistics will assist in accuracy, which is very important for Great Axe wielding Warriors that may get frustrated from missing on such a high delay weapon. Thief specific job traits such as Gilfinder and Treasure Hunter are among other important boosts that help any job.
