I always feel bad about killing dragons in Dragon Age Inquisition. Especially the Fereldan Frostback in The Hinterlands. This is what goes through my head every time I’m in this fight. And being the generous, sharing sort I am, I thought I’d put it up here for maximum moodiness.
The evil hunters invade her safe nesting grounds and attack without warning or mercy.
They slash her legs with swords, burn her wings with magic and sting her eyes with arrows and venom. She must fight. This is her home and she tries to beat the vicious attackers back. The young are hidden in the caves far above where the little two-legs can get at them. She has commanded them to stay. Some will disobey. They will smell the blood and fire and be unable to resist the call of the hunt. But she knows that most of her brood will stay and survive.
The fight is like none she has ever endured before in her long life span. Her attackers are relentless. Nasty and cunning, there are but four of them yet they appear to be everywhere. Whenever she manages to knock one so flat it shouldn’t be able to rise again, another revives the vile creature. The attacks never stop. They hound her back through her valley and she gives way. Step by grudging step.
Finally, the pain is too much to bear and she cannot help but scream. The moment that ear-piercing shriek of agony is torn from her maw she knows despair. Her children cannot hear her agony and not come to her defense. She screams again and again as some of the hunters keep her at bay while the others mercilessly cut down her young in droves. Each one, each death another bloody gash across her heart. She weeps. Scalding tears of flame leak down her face biting at every cut they cross. One eye is already forever darkened by a crossbow bolt but she can still weep. And the pain. The pain, the pain! It fills her mind and her world as she screams and forgets why she should not. Madness fills her world for a brief and desperate attack. No longer is she trying to save herself or her babies. She just wants a piece of the bastards that killed her. But even that is denied the dying mother.
As the light fades from her eyes the last thing she hears is some Qunari whooping in joy over her broken bones and the bodies of her dead children.

And also from the Dragon Age wiki I give you the fight strategy:
As you enter the initial area close to the camp (Lady Shayna’s Valley), the dragon will circle around, destroying the top of the central spire by smashing into it. Upon seeing your party she will start to periodically bombard you with fireballs. The first fireballs will be coming directly above you so try to dodge them and get close to the central spire. The dragon will change her path when you are far enough in. Standing behind the spire will protect you from this new wave of fireballs. You can also put in some hits with a mage or an archer. After a few rounds, she will eventually fly and land in the next area (Blood Cliffs). If somehow you are caught off-guard by a wild fireball, you have time to cast barrier in the time the fireball takes to travel. Be aware that this area contains dragonlings who will also attack you if they notice you.
Note: You can skip this stage altogether by running through Lady Shayna’s Valley into the Blood Cliffs.
The dragon lands in the Blood Cliffs area and this is where the real fight begins. Get your warrior in front of the dragon and all ranged members to the sides as far as possible from her. All dragons are immune to taunting, so the only purpose to abilities such as War Cry or Challenge is to generate guard. Rogues with daggers should be at the back to maximize damage. Dragons have multiple targetable parts: dealing enough damage to any leg will force her to jump to the other leg. For example, when you hurt the left leg enough she will jump to her right. When she does so, reposition your team as before with only the warrior in front. This positioning ensures that only your warrior will be hit by breath attacks, you won’t get pulled in by her maelstrom attack (where she flaps her wings and pulls the party in close while doing heavy damage), and your party won’t get stomped on. Though she can’t be taunted, she will still attack the party member with the greatest threat generation, in this case your warrior wearing heavy armor. Cast Barrier whenever possible on the warrior or any member who needs it the most.
When you cut her health to 75%, she will take to the skies again, throwing fireballs and breathing fire down a path. This attack is a little tricky to avoid as it is faster than the fireball and has a wide AoE, so it is a good idea to keep your party on the move. She will land on a ledge and call dragonlings to attack you. Although you can used ranged attacks at this point, you should focus on killing the dragonlings to stop them damaging your party. The dragon will return to the field after killing all the dragonlings and the fight will continue as per the second stage. Taking her health down to ~50% will make her fly to a ledge and summon dragonlings again. During this stage the dragon may use a roar that will stun your entire party for a few seconds.
Note: If you manage to deal enough damage at around the 75% point, e.g. with an archer dealing critical Long Shot or Full Draw damage with a powerful bow, then she will not take off or summon any dragonlings and will remain on the ground for the duration of the fight. It may help to target her head, as enough damage there will interrupt her attacks and make her forget what she was doing for a moment.
Upon reaching 20-25% health, she will proceed to the final area. Climb up the hill by following the path. If somehow you can’t get to her, your party can. The dragon will face you to the bitter end here, along with her dragonlings, although it will take longer for the dragonlings to reach the area compared to previous stages and it is possible to finish her off before any dragonlings reach your party. This area is smaller than the previous one so you might get caught by the maelstrom attack and/or get KO’d instantly by a wild fire breath attack, so this is when you should attack her all-out. She will also stun your party with her roar, but if you keep the party spread out, you’re only likely to lose one member if she follows up with a breath attack after a roar. Once you kill her, loot her remains and claim the landmark.
