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.
Heart of the Unliving This is the regen trinket every healer is going to want for the rest of the expansion. It’s the direct upgrade to Darkmoon Card: Tsunami, which you may have noticed most people were still wearing throughout tier 12. The trinket is most ideal for holy priests, who get 30% additional spirit regen from Holy Concentration, but that doesn’t mean disc priests need to back off. Disc priests are still able to utilize the spirit through Meditation (even if Rapture will only benefit from the intellect side of the trinket), which means this is the best regen trinket a disc priest can get. Both priests specs should keep in mind, however, that the healer who will benefit from this trinket the most is the one who has the most mana problems. If you raid with the same group of people week after week, you may want to distribute this particular trinket based on need.
Seal of the Seven Signs The problem with a random haste proc is that there is no real way of knowing whether or not you’ll be able to utilize it when it goes off. That’s the main problem with this trinket from a healer’s perspective. Healing is not a job that requires you to produce the most HPS possible at all times. It is a job that requires you to respond appropriately to the flow of damage in a fight. Damage is not always high, nor is it always continuous, so having a trinket that will randomly increase your HPS by increasing your casting speed is of debatable benefit. Using this trinket, there is even a risk that you might not be able to use the proc at times, since there are phases of fights that require little to no healing at all. I don’t want to make it sound like this trinket is bad however … It’s quite good, just not as good as it could be if it were say, an on use haste trinket. (I should also note for the sake of novelty, though, that the proc on this trinket can get you the mythical sixth Renew tick, provided you have enough static haste rating to begin with, about 1,800, but with the proc being random, there is really no way to make it effective.)
