Is it possible for a guardian to become something other then a Hunter, Titan or Warlock? What if a Guardian embraces all the traits of a Titan but in their past life, embodied a warlocks ideals and philosophy? Would they then become a Paladin? Would this new Class type give raise to new, more interesting ways to manipulate the Light? Perhaps a Hunter who uses the methods of a Warlock or the fortitude of a Titan? What happens in these cases?
