So after doing dungeons then heroics, I found that Blizzards healing philosophy was quite interesting.
Spamming heals and keeping everyone at full just isn't the way to play any more. It's great!
Then I did a few raids...
...And it seems nothing has changed since Wrath! It seems to be exactly the same spam-fest as before! Now, it may be that it was because I was healing with two druids - I have no idea what state they are in..
TLDR: How are you finding healing in cata raids, less spammy than before, or not so much?
