Yep, that's true.Deathwing could be good for you
But as you might know, the only way to have an army that's genuinely Deathwing, is to include the Master of the Deathwing in your Dark Angels force, which alows you to take Termies as a troop choice.
I have done this to my own army, allthough it's not actually a Deathwing force. I used one elites slot for a veteran squad as well, as I needed to buy the veteran box anyways.
But anyways, it gives me a 1500 point army with only 17 foot soldiers (of which two are characters), and moreover, it's all plastic!
