Although wouldn't the "higher ideals" choice be to save all of the people on the dreadnaught?
Of course, they'll pull a Mass Effect and screw the people who took the hard 'save more people choice'. (My Paragons all chose "Concentrate on Sovereign," figuring the lives of all the troops in the attack ships were a bigger deal than three replaceable councillors. Of course, in ME2 they had to then make the Council's ship have more people on it than the others combined... Just wait for it to be revealed that the entire hill was dug out and full of Chargers and that the ship was piloted by a single qunari.)
That's another thing, there have got to be a couple hundred people on that Dreadnaught, people with lives, friends, loved ones, who are counting on the ground team to protect them.
Thinking back to DA2, dreadnaught was the same class ship the Arishok and his forces were in when they crashed at Kirkwall. They had 'a few hundred men', so assuming every member of the crew made it to shore, we're talking about at least three hundred qunari on that shp. Maybe the Arishok was traveling heavy due to the nature of his mission, but you're still probably looking at a hundred or more people on that crew.
And I'm supposed to save the six members of the chargers because... why? Because they know my name? Because we had drinks one time? That's the motivation for me to give them special exception and not hold them to the same standard I hold every other soldier under my command?
I don't think so.
