Property stat values?

[Vandril]

I'm hoping someone smart can do some testing though, especially since spell speed now apparently affects regen spells. It's hard to separate the Mind from the spell speed when it comes to testing.

It seems somewhat simple to me. Since all(?) spells have their potency listed, we know their comparative...potency.

1. Test the healed amount of both the regen spell and the direct healing spell twice; once naked, and once with a single gear piece that has both MND and Spell Speed but does not have DET. Make sure to record the results.
   
2. Take the potency of a regen spell and divide it into the potency of a direct healing spell. We'll call the result "value P".
   
3. Find the difference between the amount healed from the direct healing spell when you were naked and when you were wearing the gear piece. That difference is how much healing the increased MND from the gear piece added to your healing spell. Let's call this difference "value D"
   
4. Divide value D by value P. The result of this division will be the amount of healing increase your regen spell gains per tick from the MND on your gear piece. Let's call this "value R".
   
5. Find the difference between the amount healed per tick from your regen spell when you were naked and when you were wearing the gear piece. Call this "value T".
   
6. Subtract value R from value T. The result is the amount of healing that your Spell Speed from the gear piece increased your regen spell's healing. Call this value "N".
   
7. Divide value N by the number of Spell Speed you gained on your gear piece. The result will be the increase to a regen spell's healing ticks per spell speed rating. Assuming the stat increases healing at a steady rate (not exponentially), then this result should be valid.

Here's an example with nonsense numbers that I pulled out of my arse:


Step 1: Potency & Healing Record, Spell Speed Gained

Direct Potency: 400
Direct Heal w/o Gear: 800
Direct Heal w/ Gear: 865

Regen Potency: 40
Regen Heal w/o Gear: 80
Regen Heal w/ Gear: 88

Spell Speed On Gear Piece: 10

Step 2: P = Direct Potency / Regen Potency
P = 400/40 = 10

Step 3: D = Direct Heal w/ Gear - Direct Heal w/o Gear
D = 865 - 800 = 65

Step 4: R = D / P
R = 65 / 10 = 6.5

Step 5: T = Regen Heal w/ Gear - Regen Heal w/o Gear
T = 88 - 80 = 8

Step 6: N = T - R
N = 8 - 6.5 = 1.5

Step 7: Regen Heal Per Spell Speed Rating = N / Spell Speed On Gear Piece
Regen Heal Per Spell Speed Rating = 1.5 / 10 = 0.15

Results: From this example that uses fake numbers
Each spell speed rating grants 0.15 healing to each tick of your 40-potency regen spell. To find out the spell speed's effect per potency, simply divide 0.15 by 40.

Now, I'll admit I'm a bit exhausted, so I may be missing some fundamental point of math, here. But it should work something like the above.

Edit: Oh, and I'm not sure how DET plays along with Spell Speed's healing increase, so I'd avoid a weapon that has DET on it as well, when testing this. It's not likely, but it's possible that Spell Speed might "double dip" from DET's increase to healing.
