Hrm, I'm not sure I'm exactly what you're after -
my tree is my alt - but I did use him as my raiding main for 1½ years before BC so I'm hopefully not that far off from being an experienced druid even in the Lifebloom Era. At about 1250 +heal I almost never shift out to HT-spam in heroics & Kara, which is about as hard it gets for me. I don't think I've ever done a non-heroic 5-man encounter where I felt HT-spam was needed since the Lifebloom patch (err, 2.1?) hit when my druid was around L64, however he did start BC with 900ish +heal or so which isn't exactly standard for alts. I've also strenously avoided pugs and only instanced with people I know. This has probably made a difference.
Even if I did have to regularly HT-spam on more encounters I doubt I'd want to go Dreamstate, for a couple of reasons. One, there are "difficult" heroic encounters - first boss in Crypts, Kargath, etc - where the damage is spread enough for bloom-spam to be a superior tactic to HT-spam even for a Dreamstate druid. Two, the fact that I have swiftmend and better blooms & rejuvs when I do go caster form to HT counters a lot of the HT efficiency difference. Three, for the vast majority of instancing just spamming blooms with occasional Rejuvs & Swiftmends on the tank is all you need to stay on top of things and in those situations trees have a level of efficiency and ease-of-play that's pretty much peerless.
Also, this question is possibly a bit too narrow to merit it's own thread. As that's apparently not enough to inhibit my reply reflex, I wonder: is replying to a narrow thread a positive act as doing so might cause the thread to spark an interesting broader discussion or a negative act as it prolongs the agony of the narrow thread and keeps other, better threads from their rightful place on the first page?
