I do agree that with the amount of "hulk smash" the ogres already have, lots magic research could very well unbalance the nation. With that in mind the idea of one magic using ogre with good research and magic picks in something other than blood would be a perfect solution. I always have a soft spot for heros, as I feel they add so much to the character and fun factor of any nation in Dominions!
So my vote is for a sixth hero
