Just some quick napkin math with this log I have. Average CS is 27,702. I have 24.05% mastery. That means I get a proc of around 6,662 from hand of light. This results in a total of 34,364 damage. My average judgment damage is 46,849. Now things like glyph of double jeporady can skew this, and it's just some napkin math I did on my phone, but you get my point. If you do the math for your own character, through sims or a log, it MAY be different. It highly depends on your mastery level and weapon damage.
Here is the log I used
And even though EJ kind sucks, it's discussed a little in this thread.
Post 198-199, some more in other parts of the thread, but you'll have to dig.
