The PAINTER of Light(Discussion)
May I present to you my new class - The Painter of Light!! A master of creating evironmental conditions! The light painter can miniputlate light to create different spectral environments to aid his group. He can create things like spectral walls to guard against arrows and spear attacks; he can create poisonous swamp conditions to degen the enemy or even duplicates of his team mates that act as a scape-goat so the actual team mate can run from danger. He can create walls closing in that force the enemy to bunch up so his team's AoE can nuke them more effectively. The painter of lights weapon is of course a brush. But not just any brush... a really, really big brush.


 * Why this is a good idea
 * If the Great Wall of China can keep the Mongols from invading then a spectral wall will keep the destroyers at bay too...


 * Why it may not work out
 * The name may turn many off of taking that as their primary profession.
 * More of a skill, or a set of skills than a profession.
