If you are not sure what class to pick when starting World of Warcraft or if you are looking for a strong alt, you can find a simple analysis of the strengths and weaknesses of each class here. Since the classes are so different, choosing the right character from the start can you save a great deal of time.

WoW Warrior Strengths

• Can wear mail from the start and plate at level 40.
• Great tank class, especially when using a shield and going deep into the Protection tree.
• One of the better classes to use for blacksmithing since warriors can use both the armor and weapons made with this profession.
• Can be a force damage wise with a good two-handed weapon and a build focused on the Arms tree or two good 1 handed weapons and a build focused on the Fury tree.
• Can equip almost any type of weapon in the game (only exception being wands) whereas other classes are more restricted. For example, a shaman can not use a sword and a Paladin can not use a bow.
• Very high hit point.
• Ability to switch roles in mid combat from DPS to Tanking.

WoW Warrior Weaknesses

• Depends on rage too much.

• Not the highest melee damage dealer.
• More equipment dependant than other classes.
• Dependency on the healing of other classes.
• Somewhat limited in PvP due to the range and magic of other classes.
• No way to reduce threat.
• No significant ability to hea.
