By reading comments from Blizzard(blue) and checking the new talent trees and the abilities that come in Cataclysm. Even by playing in the beta..
We can look in the presant beta patch notes and experience the gameplay in beta to get an idea how the future healing classes will be.
So you might get a clue of what you think is the most AWSOME healer of them all?
What do you say? And what is so awsome about the awsome healing class you think would be awsome in the awsome Cataclysm?
Just share your opinion & why.
I'm kinda between the Druid and Priest, don't know yet.
