I still don't understand why people are talking about writers and that they like "tragic stories" and so on. Please understand one thing. Her story is not completely implemented into the game (probably combination of major bugs, plot holes, narrative issues) and basically her "Infernal engine" questline is completely empty in act3. Writers can write everything they want, but if it is not implemented into the game, they cannot do anything with it. Patch 2 hotfix uses the easiest way how to improve things in such a short time and without much work. One added cutscene and few added lines of text in every act didn't bring new ending or new quest, just polished a little bit the "best possible ending" we currently have available. Writers could already have a masterpiece story with good ending prepared, but there was no way, how this could be implemented in such a short time period after release.
