Meh, I was really disappointed at the DLC. Nyreen seemed much more badass the way I imagined her, and while I liked her, she was... somehow not developed well enough. I didn't fall for her like I thought I would
Not to mention her out-of-the-blue death really left me with a WTF painted all over my face. It really just seemed like a cheap trick to set Aria on fire >.<
Not to mention the fact she kept on disappearing from the team, saying "hey, I need to meet my men" or "I need to save some civilians" and I was all like "Hey, girl, come back here! I gave you my favourite pistol!!"
What I was really missing in this DLC was the RPG, choose-your-way-through-this part. The only thing I noticed was the fact my (like three throughout the game) paragon choices made Aria refrain from killing Petrovsky. I mean, okay, fun, but... seriously? I thought I was playing the game where "each choice has tremendous effect on the Galaxy"
Well, I am kinda hoping Nyreen had survived, but I'm not really expecting to see her anywhere in the future DLC's... although I admit, I'd love that
I'm also kinda hoping for a turian female biotic class in MP along with those awesome Omega locations as new area
