Experience is a "papal" feature because it simplifies dealing with the map and complicates dealing with the opponent. And morale is the opposite – it complicates dealing with the map and simplifies dealing with the opponent. Therefore, it is a "lame" feature.
P.S.: In any case, experience is not a tool for creating balance. IMHO.
6 I disagree. With experience, it's the opposite; there's more reason to "moosh" (rush).
