Ideas and suggestions.

You're talking nonsense. If diversity means introducing more randomness, then that kind of diversity doesn't benefit the game. Specifically, with a -2 or -3 morale penalty for both players, the endgame becomes almost entirely random. And if the developers are moving towards reducing randomness (e.g., by changing resistance), then the morale penalty needs to be addressed somehow. I'm not saying that morale should be removed. My point is simply that the situation where most endgames involve a morale penalty for both players is a bad thing.
