I think the War Table was a problem in that some of the things you hear about are way more interesting than what you're doing? Instead of me dealing with the squabblings of petty Orlesians I can't give two figs about and stopping the assassination of Empress Celene that even my advisors don't care about for the most part, why can't I instead delegate it to someone else?
Did anyone else want to ignore the main plot and instead help out the Wardens defend a town from the Darkspawn? Or perhaps get involved in the dwarven intrigue plot about the writer trying to mess with Varric? What about helping bust out Miller from that prison cell she was caught in? Going out with the Chargers to witness the aftermath of places like Haven, Redcliffe (if sided with Templars) or Therinfal (if sided with the Mages)?
It would have certainly been better than trekking over the entire Hissing Wastes for that single rune that required us going on a wild goose chase? With the amount of tombs you had to track down, solve, find the key fragments and that dragon you had to fight, all in the highest levelled location in the game... it's kinda said that the amount of loot in that tomb was so dismally small and unimpressive?
Giving us some few minor antagonists that were fleshed out would have helped in some way in most of the areas, instead of some that were merely names and for the most part, left zero impression on the player? I still don't really know much or care about any of the Freemen we fought and I suspect that most people also forgot about them ten seconds after killing them? If we'd had a recognisable face, it would have given us something to fight against?
And an adversary is especially needed in somewhere like aforementioned Hissing Wastes! It's supposed to be an archaeological race, right? Well, why isn't there a Belloc to our Indy? The Venatori Leader there who's racing us to the treasure and fighting us every step of the way? Perhaps he could have even pretended to be an ally of ours at first, an absent-minded Chantry scholar in the vein of Genetivi? Leaving that final tomb and discovering a legion of Venatori who answer to him, after our spoils of war that we now have to defend, would have made that quest actually seem important?
