How much +healing is worth 1% spell crit chance?

[Wolfrig]

A simple question, I know the value changes with your gear (the more healing gear you have, the more each crit chance is worth), but I would like to know how much +healing 1% spell crit is worth in various periods of endgame (pre-raid, MC/Onyx, BWL, AQ, Naxx).

I know it's a bit harder to calculate this for paladins because we get back 100% mana when we crit, making spell crit much more valuable to us than to, say, druids or priests.

Looking forward to answers from some experienced pallies.

average 12 (less/more by 1) depend on the content

Depends on gear and what spells you're casting.

1% crit is worth both +healing and +mp/5.

Healing wise for Flash of Light spam, the equation:

0.01 * 0.5/0.43 * FoL_Amount
or 0.01163 * Flash of Light Amount

The 0.01 is the 1% increased critical healing chance
The 0.5 is the bonus healing done. I.e. If you crit a heal with a base of 800, it will crit for 1200. The difference is 400 or 0.5 of the base.
The 0.43 is the coefficient that +healing applies to Flash of Light (1.5 second spell).

So, for 800 FoLs, this would be a +healing value of 0.01 * 0.5 / 0.43 * 800 = 9.3 + healing


But, illumination also gives you mana back.
Assuming 2 FoLs per 5 seconds (pretty reasonable):
0.01 * 280mp/5 = 2.8mp/5

The 0.01 is the 1% crit chance
The 280 mp/5 is the mana cost to cast 2 FoLs every 5 seconds.

So, with your FoLs healing 800, it's worth 9.3 + healing and 2.8 mp/5. If you value mp/5 as 3+Healing, That's 17.7 +Healing per crit%.

For my FoL's doing 1000, The value is 11.6 +Healing and 2.8 mp/5 which is 20+healing. Petty easy to tinker the equations if you're frequently casting Holy Lights (way more mp/5 benefit) or if you're spamming Flash of Light more or less.

Thank you both for your replies, this will make gear priority much clearer.

And btw ketchup, how on earth can your FoL heal for 1000? They didn't even release AQ yet! I know Blessing of Light gives some +100, but that still makes it 900, while the base is 400. Coefficient being 0.43, you would need to have 1162 + healing in order to increase your FoL by 500. Even with consumables and all, that seems alot for a pre-AQ gear.
