Seems a good topic- getting to grips with the new general traits.
Zeal appears to deal with damage- if you want to use your general as a tank, then Zeal is for you. The first ability unlocked appears to be
"War Cry", which lowers enemy morale.
Authority appears to help your general's bonuses/buffing effectiveness- something such as a 10% increase in command aura, and the ability to "Inspire".
Cunning... I'm assuming it'll help with ambushes though I haven't seen a bonus for it yet. The first ability unlocked is "Second Wind".
Thoughts?
And I shall go Softly into the Night Taking my Dreams As will You
