Raigor Stunhoof

Great guide, I like the idea of putting of fissure because of the mana consumption. It could also help your teammates who need the farm get last kills more often. You're definitely right that the stun is way more valuable than the damage.

If you like the soul ring, you should also try the force staff sometime instead of the blink dagger. You can still surprise them when you need to by jumping in the fray, or you can pull someone into a dangerous situation for an easy gank. Also fun to save yourself or teammates from ganks this way.

I'm reconsidering my stance on Soul Ring. I've been using it recently with other heroes and I may have underestimated it in my initial ***esment with Earthshaker.
I think it might be an option to add to situationals, mid game, or early game. I'm going to test it's usefulness out in early and mid phase, hopefully I will run into Bloodseeker in Matchmaking.
