As a holy pal in early wotlk

Here is some theorycraft math for some of you who are comparing MP5 vs Crit and heal based on spamming FoL
This math is based on 300 seconds (5 minutes):
Number of crits = Crit % * ( 300 secs / cast time )
Mana returned from crit = Mana Cost * 0.6
Total mana returned in 5 mins = Number of crits * Mana returned from crit
Spamming Flash of Light
1% crit rate using 1.5 sec Flast of Light costing 180 mana, you get:
1% * (300/1.5) = 2 crits
180 * 0.6 = 108 mana
Total mana returned = 216 mana
In 300 seconds, you have sixty 5 second periods, which equates this out to 3.6 mp5.
Therefore 1% = 3.6 mp5 spamming FoL
Investigating what is the best way to spend item points
Each 1 spell crit rating = 1 item stat point.
Each 1 mp5 = 2.5 item stat points
It takes 22.1 spell crit rating to gain 1% crit or 22.1 item stat points.
It takes 3.6 mp5 to equal 1% crit, or 9 stat points, spamming FoL
Healing is 0.455 stat points per point of healing.
Which means, for every point of crit, you can get the equivelent in mp5, and 28.8 healing.
But, but but … crit add healing because you crit for 1.5 times your healing!
Okay, lets do the math. Lets say you have 2k healing, and have spent every stat point available into crit, you have 50% holy crit from having a base of 10% crit (from int, etc) and 5% from talents, the remaining you gained from 774 crit rating, and absolutely no mp5.
Lets calculate the base heal
448-502 base FoL
+185 healing from BoL
+105 healing from Libram of Souls Redeemed
+857 healing from your +healing (2000 * (1.5 sec cast / 3.5 sec cast base))
+ 12% healing from Healing Light talent
= 1786 – 1847 healing
= 1816.5 avg heal
Now in 300 seconds, you will cast 200 FoL, and 50% of them will be crits. So that is 100 crit, and 100 non-crit.
That is 100*1816.5 + 100*(1816.5*1.5) = 454075.5 healing.
Okay, and what about mp5, surely it heals for less
Now, lets assume the same for 2000 healing + 126 mp5 (equiv for 35% crit) + 10.00% base crit + 5% crit from talents + 1009 healing, which is what you saved in stat points from using mp5 instead of crit.
Lets calculate the base heal
448-502 base FoL
+185 healing from BoL
+105 healing from Libram of Souls Redeemed
+1290 healing from your +healing (3009 * (1.5 sec cast / 3.5 sec cast base))
+ 12% healing from Healing Light talent
= 2271 – 2332 healing
= 2301.5 avg heal
Now over a 5 min fight, you cast 170 non-crit heals and 30 crit heals.
That is 170*2301.5 + 30*(2301.5*1.5) = 474822 healing.
Its actually MORE healing, because you are getting cheaper stat points, and can reallocate those stats as healing instead of crit.
