We have some changes in 3.2 that will address some of the concerns healing shamans and paladins have.
---
We are working on a (long) post to explain some of the paladin changes. I don't have an ETA.
...We're okay though with expanding their breadth a little bit for those situations where you have more paladins than tanks or the raid is taking a lot of damage...
