I'm now about 2000g poorer than I was a week ago, with my first tier 9 piece and about a 10-15% DPS increase to show for it.
I'm raiding mostly as elemental and it occurs to me that that is the right place to be right now. I can comfortably (or even half-asleep) heal anything in the game right now apart from the Black Knight phase 3, Ulduar and ToTC, and those last three I can heal just fine as long as I'm awake. So if I stick with DPSing my way through Icecrown I'll be in a very good position when Cataclysm arrives, and I might even have pulled myself off the bottom of the DPS list by then.
Meanwhile I'm still doing enough healing in instances to keep my hand in, and attempting to keep track of the changes to (or even master) the two different sides of Grulnak is a big enough task to keep me interested.
