Big hand to @DerZauberer and @Malakree, I can't really find specifics to reply to but you've given me some tasty food for thought. I recently got a second Mawkrusha (which I'll build as the big bad G, obviously) so I'll definitely try the Gordrakkfist* as well.
* - that'd be a maxed out Ironfist in an army with Gordrakk, yes?
