Dark/Earth?

[biostem]

So I've been toying around with various builds and powersets, and was just looking for some feedback from the more experienced Dominator players out there.  I messed around with doms to a very limited degree while CoX was still live, but while going over the sets available, dark/earth seemed like an interesting combination to me.  That being said, I have some experience with darkness control, but was looking for input on earth assault and/or the combination of dark/earth.  Thank you all in advance for any insight you can provide.

 

The biggest downfalls I can see with earth assault is that it mainly does lethal damage, which can be highly resisted, and all the knocks, (up, down, back), may be annoying to teammates.

 

Thanks again!
