Spark of Hope debate
Mar 25th, 2010 by partouf
I’ve been worried for some time now to replace the Spark of Hope trinket. Not just because of the +100 spirit for mana regen (35mp5 in my case), but in particular for the -42 mana per spell cast.
A large part of the druid restoration spec is to cast hots raid-wide, and lots of them. Since this trinket reduces the mana cost with 42, with every so much casts, you get a free cast where without the trinket you could not.
However, since I no longer had another item to buy from frost emblems, except for offspecs, I decided to actually calculate what I would gain or loose with replacing Spark of Hope with Purified Lunar Dust.
The differences, obviously, +100 spirit and -42 mana per cast, against 179 spellpower and chance to gain 304 mp5 for 15 seconds.
I’ll negate my first calculation in favor of getting the numbers from comments on wowhead that say you’ll effectively get an 76 mp5 average during ‘a’ fight. (assuming ~1ppm: 15 seconds / 60 seconds = 0.25, 0.25*304=76)
To get the numbers from Spark of Hope, I turned to a log from World of Logs to get the number of casts. I copied the number of hits and crits of regrowth, ht and nourish of a Marrowgar fight, together 65. And then the number of ticks of rejuvenation divided by 18 and Lifebloom by 8 (both not entirely accurate), which is 48. Together an estimate of 113 casts in a 3:40 fight (220 seconds).
For the mp5 over time; 220/5=44 times regen
Mana gained by Spark of Hope: 35 * 44 + 42 * 48 =1540 + 2016 = 3556
Mana gained by Purified Lunar Dust: 76 * 44 = 3344
Difference: 212 mana
So you can imagine, I’m not entirely convinced if Spark of Hope should be replaced. However, the extra spellpower Purified Lunar Dust is beneficial to every spellcast as well, and should of course not be overlooked. But I can’t exactly measure that and put that somewhere in this calculation, as I cannot predict how much less I will have to heal because of it. Is it together at least 1 cast so I won’t notice the 212 mana difference? Or what about the fact that Spark of Hope prevents you from having to wait for mana regeneration, which may be important depending on the type of fight and circumstances.
In any case, I will definitely give Purified Lunar Dust an honest chance to prove itself. Should I conclude I cannot adjust to the shift of stats, or come to fights where I have to cast more often than usual, I will rethink and adjust accordingly per fight.
