Yhetees have the same stats, including the -1 command penalty, as Trolls but don't have the regenerate ability.
Yet(ee) they cost 20 points more than Trolls. Should they be the same price as Ogres - and I note that Ogres in the Ogre Kingdoms list are 5 points more than in other lists that have them.
Does the Ogre Kingdoms list need adjusting slightly? Goodness knows it's a list full of high cost units!
