[phiwum]

Never struck me that Courtly Graces would be necessary to identify the important foes on a battlefield.

Probably Tactics would give some indication of who is leading the troops. I suppose that if the political or feudal leader isn't also in charge of the fight, Courtly Graces would help one identify who he is by how he carries himself and how others defer to him.

I'd just shoot at the one with the crown, but I'm simple that way.
