I'm with OP on this. I was filled with excitement when "The Emperor's Wrath" joined my crew! That was all wiped away when a stinking ratattakki dropped him. Seriously - ONE STINKING RATA(whatever) took him out solo. Good job, chief. Emperor's Wrath is really Emperor's Wuss in disguise. That's why he left, because he was found out by the sith and had to flee for his life before the Emperor's Janitor dropped him with a sharp broom handle or something.
Now I'm torn between Kira or Sgt Rusk (I'm running as a Guardian). Kira's my girl, and she hasn't let me down yet (a little squishy, but easy on the eyes). Rusk hits hard with his cannon, and he seems to work well with my Guardian. I keep flipping back and forth between the two, wondering who might be the better.
