Searing Light is not designed to be used as a main damage skill. It is a utility skill, designed to further lower resists among other stats. Not every skill has to be viable as a main source of damage. I am not looking to homogenize every class either, just because one class can do something that gives it an edge in certain categories doesn't mean other classes should get the same thing too. I keep seeing those type of suggestions, and honestly I am not a fan. WoW was ruined when blizzard homogenized everything.
