I still maintain that this is more that we could've reasonably expected from a patch not even a full month in. Should it've been in the game since the beginning - probably, but so are many other things that get patched, that's the whole point of a patch. Now, if it was called a DLC - that would be a whole other thing (see plot-important characters being DLC-locked in Mass Effect for example).
The most frustrating thing here is the way they phrased it. We're also responsible for getting overhyped way too quickly, but the whole 'new and optional ending she deserves that will make a lot of people happy' phrasing was really unnecessary. As someone who has worked as a community manager before - not in the gaming industry, but still - I am really questioning that approach. Half of us are really more mad about that than the update itself.
I'll hold out hope for a new quest path for her later in DE or for a DLC or some other way to actually follow through on the leads. That desire haven't changed. Either give me the opportunity to work for it and fix her or truly make me feel like I did everything I could.
For the current state of things, however, I'm glad I at least won't be seeing cut to black once I reach the end.
(P.S. Did spoil the cutscene for myself and I have to say I don't understand why so many people are mad about the running at the end. It's clearly meant to be slowmo.)
