The point was that Bio communicated about the BE but never mentioned new hair and outfits. If new hair and outfits had been in the DLC they would have been mentioned -- the whole point of talking about a new DLC is to raise people's interest in it, so you mention the good things that are in it. Therefore, anyone who read Bio's communications and still expected new hair and outfits was, bluntly, a fool.
But you knew that already.
Someone asked why people thought there would be extra features in BE. I supplied a possible reason. I'm sure there are many others, reasonable an unreasonable. I have an issue with how Bioware communicates in general. Personally, while there were things I hoped for (in an ideal), I didn't expect BE to somehow solve every issue I had with the game. Don't get me wrong, I enjoy what's presented, but I also feels there's room for growth. Some of the growth can still be implemented in this game, and some will have to wait for later games to even be considered.
Ideally, Bioware might say "Hi all, we're working on x, y, and z, and we've heard what you're saying about a, b, and c. The best we can do right now is finish what we're doing, and get back to on whether or not a, b, and c are possible." Obviously, how they choose to report is their business, but there's nothing that dictates I have to be pleased with it. And I'm not sure what your point is about hyping up DLC. Jaws of Hakkon was not, to my understanding, particularly hyped up, so I would interpret that to mean that Bioware/EA do what they feel is best, rather than a hard rule of always heavily advertising.
