Well, technically, we already did do something in a cutscene. Whether or not it was awesome is subjective -- I thought it was awesome -- but does anyone remember how it was us, and no one else, who obliterated Iggy (I keep forgetting that Ascian's name) from the fight with her and Lahabrea? She was about to warp away or reincarnate or whatever it was that the Ascians did, and it was us who threw that white aetheryte and did whatever came next (I can't remember all the details, sorry!).
I would settle for something like that in future cutscenes. It'd be easy to do on SE's part, and at the same time it'd make us look awesome. Why waste time attacking and parrying when we can use a cutscene exclusive ability that anyone, race, gender, and job, is capable of using?
