Has anyone figured out which trinkets are considered BiS for us?
Trinkets with Intellect
[Core of Ripeness] and
[Fall of Mortality] - Pretty much equal at the 359 level.
[Darkmoon Card: Tsunami] - Very similar but definitely more expensive to come by.
[Tyrande's Favorite Doll] - Again, very similar but more unique.
[Fall of Mortality] - Heroic version obviously takes the lead of these choices.
Trinkets with Mastery
[Darkmoon Card: Volcano] - Would be good for an AA Priest.
[Mirror of Broken Images] - On use ability has limit PVE applications
[Soul Casket] - Easy to get but you have to click it.
Trinkets for Mana
[Mandala of Stirring Patterns] - Best one with straight up Spirit.
[Shard of Woe] - Not very good with WoW math so someone else will have to figure out how much spirit this is equal too. I do like that the on use ability is on a 1 minute CD compared to the usual 2 min.
[Jar of Ancient Remedies] - I would assume that, unless you use the ability, you would constantly have 5 stacks for a total of 515 Spirit. This might be the best trinket for regen. I am not sure how valuable the on use ability is because 6420 mana is like 1 Greater Heal and you lose the 515 Spirit for 30 seconds.
[Jar of Ancient Remedies] - Heroic version gives 580 Spirit and restores 7260, which is still not much.
[Vicious Gladiator's Medallion of Meditation] and
[Vicious Gladiator's Emblem of Meditation] - PVP trinkets that cost Conquest points but would have their PVE uses.
My Thoughts
Like I said, I am not big into doing WoW math so I don't really know the numbers here, but just from looking at it, here is what I came up with.
If you want the most Spell Power and largest Mana pool, then you should go with
[Fall of Mortality] and either
[Core of Ripeness] or
[Darkmoon Card: Tsunami] depending on how good you are with on Use trinkets and how deep your wallet is.
I am honestly not sure how the mastery trinkets compare to the Intellect trinkets as far as throughput goes so someone else will have to figure those out but from what I can tell, non-AA priests would want to get
[Soul Casket] while AA priests would benefit more from
[Darkmoon Card: Volcano].
For mana regen, without doing the math, it seems like the best ones would be
[Jar of Ancient Remedies] without using the on use ability and
[Shard of Woe].
My Choices
Until someone shows me that mastery is the better choice on these trinkets I will be avoiding those for now. Since my guild is only 8/12 on normal mode currently, the heroic trinkets are out of my reach. On these first 8 bosses, I honestly haven't had much of a mana problem. I imagine heroics will change that. So I think I will be aiming for
[Fall of Mortality] and
[Core of Ripeness] for now. On fights when I have mana problems, I will probably replace
[Core of Ripeness] with
[Jar of Ancient Remedies].
Please feel free to show me the error of my ways and do the actual math needed to make a BiS decision.
