I've killed it twice with two fairly different groups. The first time it bugged out and got stuck in a hole somehow, so I just had ranged blow her up. The second time I did it with Leliana as an archer, Morrigan as flex dps/healing, my warden as 2h dps and Alister tanking. I think we were in the late teens as a party when we accomplished it. Was pretty dicey towards the end, but some well placed hexs and a cone of cold dropped the dragon with just Morrigan alive.

It's a pretty fun fight, but it's nowhere near the "hardest." Between the high dragons, I think Flemeth is by far the more difficult of the two. The hardest single mob boss fight for me was the broodmother, because I didn't figure out you could stand on the slime to avoid the tentacles. I "killed" the tentacles every time they spawned, and the adds and her. And I had no heals in my group at that time. It was pretty intense.
