Analysis, Obsolete, Spells and Talents
Bellwether of Dark Iron (US) writes in with this great question:
I often run with a Protection-specced Paladin tank, and he recently asked me a question I don't know how to answer. It was a question of Blessings, and he didn't know if it would be better to give me Blessing of Wisdom (mp5) or to increase my Spirit through Blessing of Kings. I was unsure which would be better. I do most of my healing in Tree Form with constantly refreshing Lifebloom stacks. Would this make BoK more appropriate overall then?
Bellwether sent me this question in October, and I originally intuited the answer from my own experience and personal preference for mana regeneration. However, dusting off Excel for the recent Thorns post inspired me to do a little math to flesh out my response so that I could share it. Like most stat/gear/spell comparisons, it's helpful to convert them so that they speak as close to the same language as possible. Since Blessing of Wisdom grants pure mana regeneration, I converted the Spirit component of Blessing of Kings into the equivalent MP5 it would grant. This, of course, ignores its auxillary benefits (additional HP from 10% more Stamina, additional mana from 10% more Intellect, and any additional +Healing if you use it while in Tree of Life), but it does give us a good starting point.
MP5 from Blessing of Wisdom
The MP5 value for BoW is pretty straightforward:
Paladins can also pick up a 2-point talent from their Holy tree called Improved Blessing of Wisdom. This talent increases the MP5 from BoW by an additional 20%, from 41 MP5 to 49.2 MP5. Since this Blessing grants pure MP5 it is unaffected by Spirit or percent time inside the Five Second Rule, thus making our lives a great deal less complicated.
MP5 from Blessing of Kings
To find the MP5 value of BoK, I'm assuming 3/3 Intensity (30% mana regeneration while casting). We don't need to take Living Spirit into account since BoK is multiplicative; we need only look at the "base" Spirit on our character sheet. We can then modify the formula from the earlier Spirit vs. MP5 article to derive its corollary, the formula for determining how much MP5 is required to match the value of 1 Spirit:
Mp5 required to match 1 Spirit =
Using this formula, we can determine the MP5 contribution of Blessing of Kings, assuming we know the following information:
- Base Spirit (SPI)
- % Time in the 5SR
- Casting Regen (assume 30% from Intensity)
Blessing of Kings vs. Blessing of Wisdom
I've calculated and graphed the MP5 contribution of Blessing of Kings at 50%, 75%, 90%, and 100% inside the FSR:
Then I performed the same calculation as above assuming that I used Innervate once every six minutes:
Note: For those who are curious, I can factor in Innervate by assuming that I'm under its effects (regenerating at a rate of 500%) 5.6% of the time and outside of its effects (regenerating at my normal rate) 94.4% of the time. For simplicity's sake, this assumes it's used once every six minutes. This should be considered a conservative estimate since it can sometimes be used at one minute into a fight and again at seven minutes — or once at one minute into a shorter fight (3 minutes).
From the above graphs, note the following:
- Because BoK gives Spirit, its MP5 equivalent decreases as the amount of time spent in the 5SR increases.
- Because BoK is percentage-based, its MP5 equivalent increases as the amount of base Spirit increases.
- Without considering Innervate, even at extremely high values of Spirit (700+) and at 50% of the time in the 5SR, the MP5 contribution of Blessing of Kings is less than half that of Improved Blessing of Wisdom.
- Once you take Innervate into account, however, a very conservative FSR percentage of 90% yields approximately half the value of MP5 from an Improved Blessing of Wisdom at very high values of Spirit.
Comparison and Conclusions
Clearly, Blessing of Wisdom is going to grant much greater mana regeneration than Blessing of Kings since Kings spends a portion of its "spell budget" on other effects (increasing your Intellect and Stamina along with other stats which are mostly worthless to a Restoration Druid). Given my preference for mana regeneration, I'd almost invariably choose Wisdom over Kings unless the encounter was really Stamina-dependent (in which case, I'd be more likely to put on a few pieces of PvP gear). In general, my order of preference for Blessing requests is as follows:
- Trash Fights: Salvation, Wisdom, Kings
- Boss Fights: Wisdom, Kings, Light *
* Of course if the boss fight is an aggro-sensitive one, you might interpose Salvation before or after Wisdom.
