The Rat Ogre would be a nightmare to program because its at odds with Warband Skirmish's themes. Rat Ogres have animal intelligence, so their experience is fixed with no upgrades possible. They have no equipment by default or as options. By default they are roughly 9 times as tough as a human and far more than a human could ever possibly reach. If they could upgrade them they would need more wounds/hit points than anyone by 2-3 times as much. Defense would need to be quite high from both trying to translate Toughness and from a practical standpoint as they have no armor. Speed would be 6/6. Attacks would be 3 by default. It would be really easy to makea balancing mistake by program a human Freelancer stronger and tougher because of equipment. Basically the Rat Ogre a boss character that is supposed to be better than any human, skaven, or anything short of another big monster.
