Cataclysm Beta Raid Testing, 10/17 and 10/18

With 9 others from my guild, I went and killed 5 bosses that were open for beta testing over the past two days. I did them all as Resto. I will try to get longer comments out at some point, but, here's a video of one of the more fun fights:

Very briefly:
--Still healing almost entirely with HoT's and instants.
--But mana is a factor. You can see me pacing myself through the fight.
--There's a lot more thought than there is currently. The key fact isn't that Rejuv is used often, it's that you have think about whom you're casting it on because you can't literally just throw it out over the whole raid.
--On this particular fight, Efflorescence is pretty nice. There were some others where I got to make heavy use of it too. Here it was almost 20% of overall healing, and will be much higher in 25-man.
--The rest of the healing was a roughly even split between WG/Rejuv/Lifebloom.
