Kinetic is a weird damage type. It's really not associated with 'Light' as we know it in Destiny. We know that subclasses are derived only from sources of Light. Kinetic's just... there.

A subclass of 'Pure Light' is interesting in concept... but Light is still lacking in Lore. I suppose we'll see.

Hands down, Darkness Subclasses have to be the most popular speculative Subclass types. The lore of Guardians experimenting with Darkness is there. Perhaps we'll see some of this in the future.

Frost/Ice really isn't Light. I could see some ice- style guns, but I doubt we'll see a Subclass from it.

Poison... I'll have to do some thinking. Perhaps.
