I dont think its been mentioned yet, but I am rather curious about this.
Which agents will be in the game and will they be available to all factions or only those appropriate for it?
I doubt that Mordor would have traders for example, or the dwarves would have assasins.
Spies and diplomats should be available to all though, but some factions could have buildings that give bonusses to these agents. Isengard would probably be the best at spying, but Gondor would probably be the best at trading.
