Difficulty: Moderately Easy
Step1
The Tank. The tank is a warrior in all its glory. Though not too hot at soloing, no other class can beat a tank warrior for its sheer aggro and ability to take hit after hit. This spec is perfect for a warrior who aspires to be in groups and raids. Being a true tank helps you get a spot in most parties.
Step2
The Powerhouse. Powerhouse warriors are not the best choice if you plan to do a lot of endgame play. In raids and instance groups, powerhouses simply are not needed because there are many other much better damage dealers. Though, if you like to solo, the powerhouse is for you. Many warriors spec as a powerhouse until they get to the higher endgame levels (level 55 and up), then re-spec to become a tank to make them more useful to groups and raids. Since you start out with battle stance as your first stance, in the beginning of the game you will mostly be a powerhouse.
Step3
The Straddle-the-Fence. This warrior has a little bit of everything and isn’t too great at anything. This warrior is fine for early in the game while you are trying to decide what fighting specialization, or spec, you would most like to have. It doesn’t work for higher levels.
Step4
A warrior in combat.
Decide what character you want to play by what you like to do and how useful you want to be in groups.
