I noticed something recently about the subclasses, moreso than just their elements and jobs. They have small themes to them. For example, Warlock's theme is Push and Pull, the basics of force. Void light would be the absence of energy, and their abilities spawn black holes and are much more highly offensive. Their melee PULLS energy from the target to increase your own power. Solar is heat, the presence of energy. It is pushed outward from the warlock. One of the big notifiers of this is how their basic grenades look. The Vortex grenades seem to pull stuff into their core, while the Solar Flares release fire from theirs. post any other ideas you might have about thematics in the subclasses and other things here!
