I notice that you're a big "needless backstory" person. I'm a big infractions person, myself.
I've always been a subtelty rogue. I began playing as sub, leveled with it, and I've only been assas\combat a few times, just to try it out. I don't have any points in HaT, because I'm not a big "instance" person; I've always favored PVP. Given that I'm level 70 (without Wrath) and I've played nearly two years now, I'm pretty competent in pvp against anyone around my level.
Does anyone else open up the way that I do? I'm a big burst person. I generally go (just in pvp), Premed, Ambush, 5point Evis, then I begin spamming Hemo and using finishers as necessary. I've learned in pvp that there aren't any good combinations, it's all reactive, especially being Sub.
