1. I talked about how useless Mass Effect 2 was to the overall trilogy, so by extension, I did mention how pointless the Collectors were.

2. I didn't like the linearity of the Hammerhead missions. They were just sub-par vehicles missions. We needed more open-ended exploration like the Overlord DLC.

3. They really don't, sadly. Many of them are implied to have profound consequences, but the ending undermines this by superseding all of Shepard's previous actions.
