I would say it's partially the impression I got from the event introduction, and my own thoughts / expectations. When the reply to a roadmap wish is a referral to the group event (seen above in this thread), you kind of get the impression that this is a two way communication. Because the point of a roadmap is transparency as well as implementing user wishes. Most of the roadmaps I follow from other software have a function implemented for receiving user wishes. With the previous forum, there was at least a poll function. Now that it's gone (along with being able to see the previous poll statistics), there is no way to gauge if AC is going in a mutually agreed direction or not (user & developer). I personally feel very passive about the new features being added, and I think most people feel this way too - thus the frustration about the lack of a roadmap.
edit: The polls felt somewhat weird to me. Yes some of them were about useful features, but there was no indication of where the topic for the polls / features came from. Were they picked from a pool of ideas? Did the developers each state a feature they wanted to implement? You (we) have no clue. I can't exactly remember the features that were being polled right now, but some of them seemed so irrelevant when you think about the long withstanding wishes.
