I'm so happy - we killed Twins (ridiculously easy fight) and then headed to M'uru. We had a lot of attempts on him, and on all of the longer attempts (~5mil damage) I was either second or sometimes first on the healing meters.
I don't really care at this point whether I "win" on meters or not - I'm just thrilled that we will probably get to kill KJ before WotLK. I had resigned myself to not even killing Felmyst. I have to admit though that now we're here, and I have the reports, it is a huge relief to be back up at the top of the meters after being SO low in BT and Hyjal (sometimes dead last, ugh).
Lifebloom still made up the majority of my healing, rolling on two tanks (with rejuv), and Wild Growth second after that. That's exactly the kind of healing I would love to do in WotLK - still maintaining a buffer of HoTs on a tank (or tanks), but tossing group heals between refreshes. I really have my fingers crossed that this kind of fight will be common - I love being a hybrid tank and raid healer.
I loved it, I'm so happy now!
