It's Tuesday, what happened to my Priest?

[Neirai the Forgiven]

These are the changes for your class in 5.0.4. This list is not exhaustive and does not include glyphs. It’s purpose is to enable you to quickly see what’s different with your class.

If a power isn’t mentioned, it probably hasn’t changed much. If a power is marked as available to all specs, it may be a talent or have been changed to a core class power. If a power is marked as removed, it may be completely gone or now only part of a glyph.

[Wend]

My play style did not have to change except for the addition of sending out mindbender (shadowfiend) way more often because its on a 1min cooldown now. I need to think about mana now, but generally don't run out if I'm using the mindbender effectively.

Seems like my overall heal throughput has increased, not sure exactly why yet but I'll guess its because of the throughput boost with archangel and also grace.
