Fereldan is in a weakened state and still recovering from the blight after x amount of years. King Al probably wont have the men to spare to even think about sending them out to help as he will have his own issues to deal with. If he were a Grey Warden however, I'd start panicking because then it would be much more likely the Inquisitor would be meeting him on the battlefield.
But this depends solely on the role he will play in the game. He may not even be hoofing it around with the wardens if the DA team have decided to implement elements of the comics into the game itself. (those who have read them will know as to what I am referring to) even if Varric was present in those comics, but it's still a possibility. I'm just hoping the warden wasn't snared in that kind of situation or I will chuck bricks.
I am hoping Bioware aren't pulling a King Maric with the Warden.
