We knew what it was before the game even released. This really shouldn't be a surprise to any of you that were in this forum this last year. I'd venture to say you are not upset with this game's endgame content, you are just upset with MMO endgame content.
Also, give opinions on what the endgame should be like, and I'm 100% sure we can get more than a few reasons that it would not work, ways players would find to do unintended things, or reasons why many people would hate it. They had to take a route, and they took one that works. If it no longer works for you because you are tired of it from games in the past, that's not Bioware's fault. It's just you not liking what the masses do because of getting older or doing it so often before. There's no fault, especially with the developer.
