With the recent haste change (90 rating for 1% from 100 rating) the stat wt.s have changed some and thus needed an update. I also wanted to make a trinket list with all the trinkets scaled to 630. My stat wt.s are based on a typical Challenge Mode Healing rotation which is Flash of light. I assumed:
- Flash of Light is the primary healing spell
- Holy Shock on CD
- Eternal Flame or Sacred Shield on the tank only
- Half of the Flash of Lights are on the Tank with a beacon, and 1/2 are spot healing.
- No Beacon Talent Taken. Free to take Saved by the Light, but Also can take Beacon of Faith for some enhanced spot healing, but the name of the game tank healing in CM’s.
I also had to value Spirit, which is always tough, because sometimes you don’t need more mana, some times you cant get enough. Typically CM fights are short enough you can spam FL till the pack/boss is dead and you drink while the group runs ahead. But to be sure I looked at the healing cost of our rotation and our mana pool with base regen. I compared time to OOM with no spirit on gear with approximate max spirit on gear:
- No Spirit Spending 3000 MPS: 78 Seconds
- Full Spirit Spending 3000 MPS: 90 Seconds
So we can gain 12 seconds of healing before OOM. At about 31k HPS we will do about 355k more healing. If we converted the spirit into Haste/Crit/Mastery we would do about 129k more healing before going OOM. That would make spirit worth about 2.75 times more valuable than Haste/Crit/Mastery, but still less than intellect. Now if you don’t go oom Spirit is worth nothing. But in all likelihood you will make use of that extra spirit and be able to keep the FL spam going longer and do more healing than if you had secondary stats instead. That gives us the following chart:

As for trinkets? Much easier to make a list of CM trinkets since there are no warforged, socket, or 42 different raid difficulty variations to chart out.

That Candle! Also, just like MoP, the alchemy trinket is great, however you need to be using draenic mana potions during fights to maximize it. Many are in BF and not yet available, but if you have Candle and DMF trinket, you are rocking.
BiS Gear list? I would put together a list, but there is no easy way to use AskMrRobot or WoWHead to search items scaled to 630. You can bring up the stats if you go through gear 1 at a time, but it would take centuries to go through all the variations. In the end the stats are so close to each other you can do well with any variation, even pieces with versatility, the total % variation is going to be small. As an example:
Total Stat Wt. of perfectly itemized piece: 226
Total Stat Wt. of worst itemized pieces: 242
Percent difference: 6.5%
That is as big of a difference you are going to get. If you have a piece with say Versatility and Crit, worst and almost best stats, it is 3.6% worse than a perfectly itemized piece. Peanuts compared to the elephant, which is great tank/group stun and cooldown usage!
