I love the monsters of the WoC book and I think that they add variety to the endless plate armored legions. Dragon Ogres are surprisingly great! They are fast, have 4 wounds, and can get up to Strength 7! They make great flank chargers as my Warriors waddle up the middle.
I converted these out of Gors and DE Cold Ones. I wanted my Dragon Ogres to look more like miniature Shaggoths than Ogres.
I still need to either convert a 6 one or make a little unit filler. I can't figure out how I want to run them either 3 or 2x2 (No rank bonus though) or 3x3 (expensive!).
I had to green stuff some fur where the two models connected.
