This has been discussed already but it seems that we may have 3 focuses (sub-classes) to choose from per class and not just 2. Also someone posted a theory that each of the sub-classes is based off of one of the 3 element types in Destiny: solar (fire), arch (lightning), and void (darkness or shadow?). That would mean that the hunter is missing void, titan is missing solar, and the warlock is missing arch. However the super abilities for each of these hidden sub-classes (if there are any) are still unknown to us. This brings me to a question. If you could choose the super for each of these missing sub-classes what would they be? Please keep in mind the class and the focus' element.
