Let's see:
One month before the EC came out, I posted a list of things the EC would have to feature to save the ending for me. The EC featured 90% of what was in that list.
Ever since ME3 came out, I repeatedly asked for more content for the ME2-exclusice characters. The Citadel DLC will apparently give me that.
Then, maybe I was just guessing right, but the EC Synthesis features some elements of my pre-EC interpretation.
Leviathan fixed the lack of foreshadowing of the Catalyst, anchoring it firmly within the ME universe, and Omega lets me save Petrovsky, something I also asked for, though they probably put that in before my input could've had any relevance.
I feel that the ME3 team realized a lot of what I wanted and posted about. As I said elsewhere, reasonable expectations, constructive criticism and a calm voice (I haven't been always that, but I try) can get you a long way with Bioware, and I think most of those claims of "Bioware not listening" have more to do with unreasonable expectations.
