Seriously, I was having a little bit of a conversation with someone on Instagram on this matter where I said:
Just a shame we get nothing, not even an alternate appearance pack or some shit.yeah truly Mass Effect had Bring Down the Sky (which was great), Mass Effect 2 had Lair of the Shadow Broker (the best!) and Mass Effect 3 had Aria & Omega (Which was a lot of fun to finally ave her in your squad). Of course Citadel doesn't need to be mentioned, that's a given. From Ashes was more a day 1 thing and Leviathan really shined some light about the Reapers.
