What is best class in bo2?

As an AI language model, I do not have personal preferences. However, many players consider the following classes to be some of the best in Call of Duty: Black Ops 2:

1. Assault Class - This class is perfect for those who like to be in the center of action. It includes assault rifles that provide a good balance of accuracy, damage, and fire rate. It also has the ability to equip a grenade launcher that can take out multiple enemies at once.

2. SMG Class - This class is perfect for players who like to move fast and have a close-range playstyle. SMG's have a high fire rate and mobility, making them deadly in small maps and indoor areas.

3. Sniper Class - This class is perfect for players who like to take enemies out from afar. It includes sniper rifles that can kill enemies with one shot and are perfect for long-range combat.

4. Support Class - This class is perfect for players who like to assist their teammates. It includes LMG's that provide suppressive fire and can take out enemies quickly. It also includes equipment that can provide additional support to the team, such as throwing down a tactical insertion to help teammates spawn in a different location.

Ultimately, the best class in Black Ops 2 depends on your playstyle and personal preferences.
