A few random Queries

[Alneyan]

Without any kind of addendum, here comes a few questions I have been having while playing Dominions:

1) Do the various Quickness effects (Boots of Quickness, Quickness spells, blessing) stack, or is the best bonus the only one applied?

2) Do squads risk losing morale if they are hit, even if no actual damage has been done? An example would be an archer attacking a high-protection unit. Or is the archer basically doomed in this case

3) How should I effectively use cavalry? If I only use a few of them, they do not stand a chance while attempting to strike in the rear of the enemy army. Or should I only bother with the elite cavalry, such as the Knights of Avalon and their ilk?

4) Has there been an interest for games played with a high or very high research cost? I am under the impression that normal research cost is the norm, but then, I have only seen a few MP games.

Edit: I knew I had forgotten something:

5) When playing a stealthy game (hide, hit'em hard, run like the winds, repeat), how would direct strikes against the enemy forces be made? Going the stealthy way seems to mean having several smaller armies, and possibly weaker than their enemy counterparts. Or is the purpose to weaken the enemy so much that recruiting new units or even upkeep becomes a problem? In other words, how should a stealthy army finish the enemy off?

Thanks in advance for your answers!
