There were five potential healer trinkets added in patch 4.3, some of which have their pluses and their minuses. If you're a holy or a disc priest and you're not quite sure what trinket you should be taking this tier, let me help you narrow it down. I'll give you a hint, though -- they're the trinkets that everyone else will try to kill you for. Watch your back!
- Windward Heart As far as healing throughput goes, this is currently the best trinket in the game. Many healers are reporting its doing up to 5% of their healing in a fight, and since the heal is a smart heal that will target the most injured member of your party, you know it's never going to overheal anyone. The internal cooldown is 20 seconds, meaning you'll see the proc going off constantly as long as you keep healing. There is some debate on whether holy or disc will benefit from this trinket more, since holy priests are typically healing more targets and thus more likely to get a critical heal, while disc priests are known to have more crit because of talents like Renewed Hope. First off, it doesn't really matter who benefits from the trinket more, because it's best in slot for both specs. Second, who it benefits more has to do with your raid role, not your spec. It's true that a holy priest is more than likely going to be acting as a raid healer, but disc priests will occasionally fill that role too, just like holy priests may occasionally tank heal. Because raid roles change from fight to fight, I would encourage you to not be that jerk who tries to make a case for it by waving his spec around.
