The least played has to be Warrior. Everyone who is a DPS and think their class is the least played based on DF results: When you get paired in DF the system tries to make it so there is one melee and one ranged DPS, if there is not they try to atleast make so 2 people are not the same class. Therefore it is easy to think there is no players of your own class if you use DF as the poll.
