The Barbarian originates from Mount Arreat and is renowned for his near-legendary, dual wielding furies which can be unyielding and incredibly potent.
In Diablo II, the Barbarians were also the characters that possessed the most powerful double weapons intended to deal the maximum amount of damage as possible.
Most gamers immediately think of using the Barbarian when selecting a Diablo III class due to some simple and well-known reasons. They view the Barbarian to be the most powerful 'tank' in Diablo III. The barbarian also has unmatched brute strength and can typically be equipped with the greatest advanced strength based gear, which is hard to use with other Diablo III classes. The Barbarian is also able to easily handle enormous mobs using the devastating whirlwind power.
Another advantage of using the Barbarian in Diablo III is that they are the one class that is able to hand out the most melee damage to opponents. However, this can only be done if they are equipped with large amounts of strength and the right equipment. The Barbarian also happens to be the class that possesses the most health in Diablo III. Again, this is only possible if the Barbarian is built using the right skills and gear, this way they can take in a lot of damage while dealing their own punishment. This is the reason Barbarians are always welcomed into other parties, no matter their skill level. Having a Barbarian on the frontlines of the battle can absorb a lot of damage from opponents and save teammates.
The disadvantages of the Barbarian are certainly their incapability to utilize magic like some of the other classes. For that reason they usually have trouble with bosses because regardless of their health level, an attack from a boss is typically extremely damaging. Melee attacks can also be restricted because you basically rush into battle and it could possibly be fatal without the right teammates backing you up.
Ultimately, gamers who decide to play as the Barbarian must not be timid and be prepared to make sacrifices for the better of the team. If you aren't afraid to put yourself in harm's way then being the Barbarian is an excellent choice for playing Diablo III, just make sure you are prepared.
The best way to be prepared for using the Barbarian is to get a good Diablo III guide that can show you exactly how to gear your character for battle. Knowing how to best equip your Barbarian will make it much easier entering boss battles and picking up those legendary items and gaining the most gold.
