Maybe for Warlock they might add a support class that enables it to heal players around him/her which I assume will be arc or they add a new type of dmg (unlikely). For hunter class they might add a more ninja or stealthy subclass that's based on ranged damage because hunter is all about the offensive! It would void dmg! #MyClass For Titan I have no freakin idea because you get to choose to be on the offensive or defensive. I think the next subclass will be solar. However these r just my ideas and I could be wrong. Anyway CANT WAIT! :)
