So, we're getting a class tomorrow 100% (pic related).

The Last Titan will almost definitely add Artificers or Astrologians.

What could Midnight add that'd be fitting for either Void, Light, or Quel'thalas? Of the classes on the leaked class survey, the only ones that seem fitting are Battlemage/Warden, Witch, Leywalker or w/e, or Bard.
