My group's really been enjoying the co-op adventures, but they seem to be treated as a poor cousin to the main line (blister packs, no printed quest guides, etc). We tend to play them to the exclusion of the campaign, these days. Our only complaint is there's not enough of them.
What's the community's general reaction to the co-ops? Do many others share our opinions, or is co-op mostly a side-light? Do you think there's enough support for FFG to do a big-box co-op expansion?
