Return of the RIFT character header images! Run away!
I have to seriously question the "super positive response" that you are seeing to scenarios. I only see my small slice of the WoW community, of course, but what I'm seeing tells me the opposite. The only people I knew that ran regular scenarios were for either daily valor or guild gold, and they didn't like doing it. Heroic scenarios are a little better because Blizzard made the rewards awesome and forced people to go in with a full group. If Heroic 5-mans were the same way, then they would be far more enjoyable to heroic scenarios.
I know this isn't a question, but I feel a need to respond to it. What I tend to see personally is that people who play only healers or only tanks dislike scenarios for the most part. People who primarily play DPS (like myself) enjoy them quite a bit. As a DPS player, queues for dungeons and raids are (were?) so absurdly long that I stopped bothering. Scenarios didn't have that problem, plus they give me much more freedom in how I played. Scenarios had me digging tools out of my belt that were never relevant in the tank/healer/DPS tinity, but made a big difference in scenario performance. Not being locked into the trinity is refreshing.
