I really liked the wartable.
I thought it would have been kind of neat if all of your different choices in the game had an affect on the approval/disapproval of the various factions (such as the Mages, Templars, Wardens, etc). And that your approval with those various factions would have affected the missions that you could do at the wartable. And it could have had various cutscenes based on approval, just like your inner circle has.
All of the different side quests you do could have an impact on the approval of the factions, and allow you to recruit more soldiers to your army of that faction type. Doing wartable missions might cost soldiers requiring you to keep faction approval up so that soldiers can be replaced. If you have high disapproval from a faction, they might try to leave your army or create uprisings that you have to deal with (in an actual cutscene, not just wartable text).
Kind of like, iirc, you had to gain a certain amount of approval from the Dalish by helping them before you could recruit any of them.
Your advisors could have served to direct you on how to gain approval or avoid losing approval with the factions. Or tell you about rumors that are affecting your approval. Or whatever.
It could have made the side quests much more meaningful I think, and your various *big* choices about who you side with would have more of an impact on the overall goal you were trying to achieve. The game wouldn't feel so much like an implication that you should complete all the side quests, but rather make a strategic choice about what side quests to complete or ignore.
Might be too strategy-game, though and less rpg. I dunno. Might have been cool.
