This past week, I finally got access to the Mists of Pandaria beta, which means I've had lots of shiny new stuff to play with recently. As a healing priest, I gave a thorough look at both holy and discipline priests and found a lot of things I felt I should report back.
First, let's start with Chakra. Before I even finished downloading the beta client, I heard complaints from other priests saying that Chakra states had turned into stances (think warrior stances). The concept of this intrigued me, but when I finally got around to toying around with it, I didn't really know why anyone would think too much of it. The stances simplify Chakra, so rather than having to press two buttons to change to Chakra: Sanctuary, all you have to do is hit one. If you want to switch again, there is a 30-second cooldown before you can swap.
