Even with the most recent changes the priest racials are way unbalanced. Fear ward is so far and away the best racial that it's not even funny while the night elf priest racials are useless. I don't even hotbar any of the nelf priest racials.
With the expansion and new priest racials being brought in with the expansion races is there any chance of some sort of better balance being brought into being?
There are no plans to change priest racials at this point in time. Like anything else though, it is something that could be looked at in the future if we feel there is a need.
I don't know when we will be releasing the other racials publicly at this point in time. Sorry. There is a lot that is being worked on for the expansion as many of you can understand and the list of things that we want to do at some point or revisit is very long.
