Congratulations, you have chosen to play a Warrior. If this is the first time you have played a Warrior you should find this information helpful to help get you going. Here we will give a general overview of basic Warrior play and some points on getting your Warrior on it's way too the higher levels A.S.A.P.
The Warrior of World of Warcraft is in many ways stereotypical to the Warrior that most people normally think of. He/She is strong, resilient, a master of hand to hand combat and does not cast spells. This however does not mean that they are without magical type abilities. What I mean by this is that the Warrior has many skills and talents that can effect either their friend's or their foe's in ways that emulate magical spells that are cast by other character classes. In one of my favorite fantasy novel's it was said that dragons did not use magic because they were magic. This is kind of how the Warrior uses his/her special skills to produce a magical type effect.
The Warrior is what I like to call a very manual class. Everything a Warrior needs to get by in World of Warcraft he/she has to get the hard way. What I mean by this is if the Warrior needs to heal themselves they have to use a healing potion or bandage which they either purchased or received from another character. The Warriors strengths, buffs, debuffs, etc. are all due to the equipment that they have, not due to natural abilities. Because of this lack of natural abilities a Warrior is quite vulnerable at the earlier levels. If you are going to play a warrior, I recommend staying with a group as a tank until you get yourself some good gear, and then play solo here and there until you feel capable to go out on your own.
The Warrior can be specced in two ways. If you want to be the hero of your group, spec your warrior to be a Protection warrior. The Protection deals less damage but can handle more damage. The reverse of this is the Arms/Fury warrior, this Warrior is specced to deal great damage but can't take the damage of a Protection Warrior.
Some points to consider when choosing a Warrior race:
For the Alliance:
The draeneis' Gift of the Naaru gives the Warrior a much needed healing ability and Heroic Presence is a great benefit when group playing. And of course they also have Shadow Resistance.
The dwarves Stoneform ability is naturally of benefit to the Warrior. Mace Specialization can be helpful.
The gnomes have Escape Artist, and their short stature can be helpful.
The Humans are good for most classes with Diplomacy, but their Sword and Mace Specialization is most useful to the Warrior.
The night elves Quickness, Shadowmeld and Wisp Spirit are all beneficial to the Warrior class.
For the Horde:
The orcs' are probably the best horde race for the Warrior with their Axe Specialization, Blood Fury and Hardiness.
The forsaken can assist the Warrior class with Cannibalize and Will of the Forsaken.
The taurens' Endurance bonus of 5% to base health, stun effect of War Stomp and Nature Resistance are great for the Warrior.
The trolls are close to the orc's as they give the Warrior Da Voodoo Shuffle, Berserking, Regeneration and Beast Slaying, all very helpful to the Warrior class.
The Warrior uses three different stances when fighting in World of Warcraft. The Battle Stance (offensive), Defensive Stance (defense) and Berserker Stance (berserking or rage moves). The Warriors battle cries are used to help his/her group like Battle Shout, or to hinder their foe's like Demoralizing Shout. Use these shouts as they become available to you, you will find them very helpful.
The warrior levels up pretty steadily, just use some common sense and think ahead about which direction you want to build your Warrior.
Hope you found this helpful.
Thanks and Happy Gaming
