I won't be getting it because I have enough companions as it is. I was thinking of something along the lines of more missions or planets to explore or even continuations of current missions. I would love to see a dlc that brings more in from ME1 but I know that will never happen.
I have to join the chorus in saying it was a fun mission, and I find Kasumi a really good squad member - she's got overload for non-organic enemies, very helpful, and that shadowstrike is badass. And her flashbang grenade ends up being very useful too. I've found myself using her alot. I just wish they had fleshed out the character so you could talk to her like you can with other team members.
To recap: I found the comp screen during the Samarra mission. Went to Illium, was automatically thanked by Thax's associate. The end.
Saw the Asari on the phone, freaking out about Thax. I thought to myself I wonder if there's more to this.
Ah, I see -yeah, that was it... the only reason I mentioned going back was the first time I played, I never returned to Illium, so I thought it was even more minor, but on a second run through, I happened to head back there and was mildy pleasantly surprised.
