How about instead of making it a set damage amount, you make it do a percentage of any given skill (including crits)? For example, 35% dmg of the skill used: Let's say you use Force Opening that does 8000 dmg at Lvl 70, Flash of Light will do 2800 dmg...then if you use Sting that does 5000 dmg, FoL will do 1750 dmg. Much better scaling that way and actually makes it useful (and not overblown at early game).
