Our goal is not to make healing more difficult. Note that nowhere in the above did I say that a problem with Mists healing is that it was too "easy." We want to slow down the pace a bit, and for the challenge in healing to lie more in making decisions about spell usage and targeting, and less in twitch-reaction and sustaining a DPS-style rotation. This also means that the cost of a mistake is not a dead player, but rather a more injured one, giving you a chance to fix your error.
We've reproduced Watcher's post in full after the cut. For the most part, I'm interested to see if Blizzard actually succeeds with their goal of slowing down healing.
