You forgot no aging (especially for humans, as they won't die from wounds, it's too cruel with an aging system).

More seriously a total conversion mod to use the dominions engine to make the true sequel of MoM would be really interesting (but moddable xp effects are ultra needed to make a game with important heroes and this xp system need also to be able to give different effects according to the unit, for things like make mages gaining picks or scouts special thievery/ninja skills).
