So i noticed just now that there is a faint little box where a third subclass could go just like how there is a faint box when looking at guns for more spaces to hold more guns or armor in your inventory, or for that matter like the faint boxes showing you how many inventory slots you have. What is the possibility of a third subclass for each class and if there was going to be one, what could each one be cause as obviously seen in game each class is missing a focus on one elemental damage type. So, Arc for Warlock, Void for Hunter, and Solar for Titan? I would like to hear others thoughts and opinions.
