Not really to be honest... which is a shame as I've always enjoyed my priest. I don't think we're underpowered like a lot of people seem to be crying about (from a holy perspective anyway), at least I haven't had any issues with heroics. Playing with guildies who aren't stupid helps I guess, haven't even touched the dungeon finder.
It's not that that I've found it hard to adjust to the new way of healing, it just feels they replaced flash heal with heal and I find myself only ever using one chakra state anyway. It's just dull. If you need to use other spells you pay a mana penalty. Seems pointless having an arsenal of spells (one of the things I've always loved about priest healing) and basically being forced into using only a couple. Having a small cooldown on a spell like fheal to prevent spam would probably be better but oh well...
I haven't played in 10 days or so, a bit over it. It's summer, may as well just unsub and enjoy more free time than usual
