Clarifying Puncture

I believe I one shot white mobs with Puncture on a Crit. I don't believe I can one shot blue, yellow, or orange mobs with Puncture.

Buffing Puncture's stationary damage helps melee more mainly because melee is more likely to stay there longer. Every bit of extra damage helps, since the faster you kill the mob, the less time is spent with the mob hitting you.
