Right now there's a lot of "Holy crap what is going on with my class/spec" right now, but I'm fairly certain within a few weeks people are going to adjust, Blizzard will adjust things appropriately (more spirit on my gear please >.>) and we won't feel so overwhelmed.

I really, truly believe that in the end all the changes will amount to better communication and better players. I believe we're going to go back to the lively discussions in dungeons as healers and casters drink their mana up... for the rogues to put kick and sap back on their bars... for warlocks to utilize their succubus and priests use mind control.

Keep your chin up healers!
