Combat Regen (per 5 sec) = (Total Mana*0.02) + (1.1287*SPI*Meditation%)
Combat Regen at Level 90 = (300k*0.02) + (1.1287*SPI*0.5) = 6000 + (0.56435*SPI)
Passive gain = 0.56435*300 = 169.305 mana per 5 sec
Rapture gain = 300*1.5 = 450 mana per 12 sec (187.5 mana per 5 sec). Highly improbable to get Rapture exactly ever 12 seconds, so this number is skewed higher.
Passive + Rapture gains = 169.305+187.5 = 356.805 mana per 5 sec
Returns 6% of total mana (18k at level 90) every 2 minutes. If used on CD, that's 9k mana a minute, 750 mana per 5 sec.
With Hymn of Hope, total mana would reach 345k, yielding a 20.7k mana return with Arcane Torrent (862.5 mana per 5 sec).
If I'm not stupid in terms of my math, then Arcane Torrent is the clear winner from a mana regen standpoint. Please correct me if I'm wrong.
Thank you so much, I was unable to check out if somebody answered to my question, seems like Blood Elf is the clear winner in this case then
Panda vs Belf ....... I thought the food buff for Panda was supposed to be very good but I know Arcane Torrent is awesome if you have mana issues.
I recently switched to Goblin for the increased haste. Also makes it easier to hit the haste for holy (about 16.66% for extra Lightspring tick).
Ellumina is quite correct. From a mana regen standpoint, Arcane Torrent is frankly overpowered. At least compared to the competition.
Then again, it is offset by the huge manacosts to cast a spell. The racial really boils down to 2-3 extra casts of flash heal per raid fight, assuming you use it vigilantly.
And that, while good, is not really gamechanging.
So... play what you like. If you really want to min-max mana though, yes, blood elf is the way to go!
