Remember, There Are No Defined Classes
The Division is all about playing the way you want to. Freedom can be a great thing, but it also means that you’re going to have to make choices. While you can change your gear as much as you want, changing skills isn’t so easy. With that in mind, you’ll want to try and choose early on what kind of agent it is that you want to be.
There are three trees you can unlock (Security, Medical, and Tech). Each one offers Skills and Talents that can serve players in specific ways. Tech will focus more on crafting and using abilities, Medical with healing and buffing your party, and Security focuses on defense.
As you get a feel of the game and its mechanics, you’ll find yourself growing comfortable with certain methods of play. Then it’s time to start deciding on what build you want going forward. Find yourself playing the support role? Go for a Medic-centric build. Just remember, do whatever you want as long as you can make the investments.
