You'll be spending more time giving them orders than the other way around. A strong backing from characters, however, grants legitimacy to the Inquisition. To start the game you're less known. By the end of the game, that's less of a concern.
Hey Allan (hope you don't mind me calling you that),
wouldn't it be more prudent (it is too late now to change that, is it?), if we had several candidates for each position and it being up to us to decide who would fill which spot on our "council" (it is like the small council on "A song of Ice and Fire")?
Would have been nice (note: of course all the people available for the spots should have some kind of experience with such a position - making this a fail option does not sound all that great to me ^^) to decide for yourself who leads your armies, who manages your ressources (that whould be what "scribbles" does, wouldn't it?), leads your spies (not that the position doesn't fit Leliana like a well made glove) etc.
I myself think that for example Cullen is not Ideal to lead an army - why?
He was - only - a Knight Commander in charge of the Templars of Kirkwall before (after Hawke takes out Meredith), he has no experience in siege warfare, doesn't know much about integrating mages into an army (templars don't normally fight alongside mages, firstly because they are afraid of them (some even hate and demonize them) and secondly because their abilities interfere with mages, too), nor does he know how to command in the field and live in the field (war-camp) etc.
A chevalier or somebody similar would have been far more logical (!) - or even a dwarf...like the Lord who becomes an Outcast if you don't make him King in DA:O (!)
greetings LAX
ps: It seems too chantry heavy to me, too (there are certain people who would probably listen to us more easily if we didn't drag so many chantry people (Cassandra, Cullen, Leliana, Vivienne (more or less)) along with us (!), like the mages or the elven people (after all, the templars hunt down their keepers and their firsts without proper cause - like it's a game!))
