Yeah, maybe the solution should just be simpler.

I still think you could make it so no-starsign would shift the element type to a random one (and starsign doing that), and add (Demon Hunter LV) bonus elemental magic damage whenever you attack an enemy with any DH or Soldier skill based on the enchant's element.

Less gimmicky and more straight to the point for what this skill's best iteration would ever be.

Here's my final version idea, disconcerting the other:

Bonus Bloodshed

Turn slashing to style. Upon shifting to, or starting your round (excluding the start of battle) in Reaver Stance, gain a random Elemental Augment (or the element of your Starsign, if applicable) for 1 round.

While the Elemental Augment is active, Demon Hunter and Soldier offensive skills will deal protection-ignoring bonus elemental magic damage, equal to your Demon Hunter's class level.
