With a character that to most people is as little defined as she is they could have probably pulled it off. But not like this.
The way she is portrayed in this video is the way i would do a Grom Hellscream or something. A character many people already know - he has some great feats and stuff behind him. We believe he is a great warrior so him just coming in and slaughtering some nameless npc's would be ok. But for Draka we need some character building before she is even halfway interesting. Like before we actually care what happens to her
