Spell Crit or +Healing

Edit #1: Put the real figures in.

I currently have Breastplate of the Lightbinder from Maiden I think Terestian Illhoof. This seems like a really good breastplate.

Last night I got Glowing Breastplate of Truth. Now this drops a fair wack of +healing and replaces it with Spell Crit.

I'll fill in the figures later when I can look at the old chest piece but the stats aggregate looks likeHere's how they measure up:

Armour (1450 -> 1607) +157
Stamina (28 -> 39) +11
Intellect (40 -> 40) +/- 0
Healing (88 -> 53) -35
MP5 (13 -> 10) -3
Spell Crit (0 -> 42) +42

So what is worth more +Healing or Spell Crit rating? What will give more healing over all?

OK Here are the assumptions. (Still need updating)
HL Base Heal 3220
FoL Base Heal 763
Original Crit 23.1%
Original Bonus Heal 1853

Over the course of a 10 minute fight you could spam:

Flash of Light (400)
76.9% of these will hit for average of 1558 that's 479,221 healing.
23.1% of these will crit for 2336 that's 215,930 healing.
For a total of 695,151 healing.

or Holy Light (300) - 2 second cast time (Light Grace FTW!)
76.9% of these will hit for average of 4543 that's 1,048,080 healing.
23.1% of these will crit for 6814 that's 472,249 healing.
For a total of 1,520,329 healing.

Now we'll swap out the breastplate and amend some assumptions
New Crit 25.0% (+1.9%)
New Bonus Heal 1818 (-35)

So over the same 10 minute fight:

Flash of Light (400)
75% of these will hit for average of 1543 that's 462,877 healing.
25% of these will crit for 2314 that's 213,438 healing.
For a total of 694,315 healing.

or Holy Light (300) - 2 second cast time (Light Grace FTW!)
75% of these will hit for average of 4518 that's 1,016,562 healing.
25% of these will crit for 6777 that's 508,291 healing.
For a total of 1,524,843 healing.

So it looks like my Flash of Light will go from 695K to 694K, a loss of 800 healing and my Holy Light will go from 1520K to 1524K, an increase of 4,500 healing.

OK, so these figures I have plucked from the air and rounded. The spell crit is actually 1.9% increase and that does not take into account any increase from an intellect increase. It also assumes a loss of 50 healing. It may be more, it may be less.

When I get home I've gotta get the real figures and plug those in.

OK, so these are the nearest figures I can use at the moment, I stuck them all in a spreadsheet and that's what I came up with. I used the actual healing and crit strike changes, but I calculated the base heals from my latest performance in game because I can't get to any sites, whilst at work, that tell me the actual base heals.

At the moment it looks like the new breastplate wins by a whisker assuming I use at least 20% Holy Light(which I do). I do lose a little Mp5 but gain armour and stamina (whoopy do!)
