We should just have these original subclasses for the whole game in my opinion.

You're 100% correct this isn't Avatar. Watching the show by myself was actually fun and later discussing it with friends. On the other hand Destiny is pretty mediocre when playing solo but shines once you find a clan to do daily activities with(Raid. Strikes, Crucible) [spoiler]Yes yes, kids talking about random subclasses like ice, earth and even life reaper. I read your post.[/spoiler]

The whole Void argument had me thinking. Came across this, via wiki: [i]Void (ether) 空 Kū or sora, most often translated as "Void", but also meaning "sky" or "Heaven", represents those things beyond our everyday experience, particularly those things composed of pure energy. Bodily, kū represents spirit, thought, and creative energy. It represents our ability to think and to communicate, as well as our creativity. It can also be associated with power, creativity, spontaneity, and inventiveness. Kū is of particular importance as the highest of the elements. In martial arts, particularly in fictional tales where the fighting discipline is blended with magic or the occult, one often invokes the power of the Void to connect to the quintessential creative energy of the world. A warrior properly attuned to the Void can sense their surroundings and act without thinking, and without using their "physical senses".[/i] So technically, it is an element. I'm pretty sure Bungie wouldn't just throw it in there without doing their research, in some fashion.

They could do a blend of all 3 classes and call it Prismatic.
