I have been playing my Resto Druid ALOT recently, and I am rather impressed with how much healers have to play with, especially as far as Resto Druids go. You can primarily HoT, or you can be a Nuke healer. Or you can be a combination of both.
I know that a lot of Druids are upset about the upcoming Lifebloom Nerf. I can see where it would really hurt some people's healing styles. It will most likely not effect mine much at all. I do use Lifebloom a decent amount, but it is usually nowhere near my top healing spells. I use rejuvenation a lot. I also make good use of regrowth, wild growth, and Nourish.
My normal kind rotation usually consists of a rejuvenation, followed by a Regrowth when they have taken a bit of damage. I then usually fill in the damage with Nourish until I need to renew my Rejuv and Regrowth. If there is a bit of damage going on to the non-tanks, I work wild growth into the rotation. Wild Growth is really a wonderful spell and I would not leave home without it.
I pretty much never use healing touch. Like ever. The cast time is just too slow. It is only really useable in Nature's Swiftness situations. I also do not get much use out of Swiftmend. This is an ability I really need to use more, but have forgotten about.
I think that with the kind of rotation I am using right now, the Lifebloom nerf is not going to hit me near as hard as some other Druids out there.
Besides rotations, there are also reactive and proactive healers. You need to be proactive in most raid content (if it is challenging). You need to be reactive on raid healing and proactive as a tank healer.
What kind of healing style are you? Are you a chain heal fanatic? Are you a pew pew Disc. priest or a big heal Holy Priest? Are you a flashspammer or a Holy Light Spammer as a Holy Pally? There are many different ways to heal with each class. If you get nerfed in one area, just figure out what else works. It is not the end of the world as we know it. Just a chance to show that you cannot hold a good healer down.
