Just wanted to post up that I am a huge fan of the Breen being used, and how they are implemented in the game. I find them both funny, and interesting to deal with. With the somewhat humorous dialogue, and interesting sound effects, gestures they make, I kinda feel bad killing them. I swear that when I am running my daily episode, I can hear them yelling (in their breen voice) at me, or at each other.
If anything, I wished more NPCs were vocal (but not too much) during battle.
If we ever get to add species to our BOF crew, I want a Breen Tactical officer!
