Could it be true? Is JC/Tailoring now a viable option for min/maxing my dps with the new cloak enchants?
Please Discuss.

Copy pasta from a post I made on my guild forums:
Benefit to caster (post patch 3.1) is the lightweave embroidery which will give the caster a chance to increase spellpower by 250 for 15 seconds when casting a spell.
Assuming this is like the current lightweave embroidery, there will be about a 50% chance to proc with a 45 second internal cooldown. Since there is a chance that the effect will fade before you finish casting a spell, I will assume that on average you will miss about 1 second of the effect. To calculate the time that it will take to proc on average once the cooldown is up, I will also assume a 2.25 second cast.
2.25 * 1.5 = 3.4 seconds average to proc when available
250 sp * 15 seconds / (45 + 3.4) seconds = 77.5 sp
Overall benefit to caster = around 77.5 sp
Overall loss to caster = 23 haste (since the embroidery doesn't stack with the haste cloak enchant)

As I mentioned there, I'll mention here: I'm a comm major, not a math major, so check my math, but unless I'm mistaken, that should reflect it's benefit reasonably.
Translating this for my character, I get about 1.31 dps from each point of sp and 1.22 dps per point of haste (numbers from Rawr in a situation where I have optimal buffs). Using these values:
1.31 dps per point of sp * 77.5 sp = 101.5dps gained
1.22 dps per point of haste * 23 haste = 28.1 dps lost
Net gain = 101.5 - 28.1 = 73.4 dps gain overall
Comparing this to JC for my character:
The Dragon's Eyes gems replace a purple and two orange gems. I also get the socket bonus from my chest piece (6 haste).
3 * 32 sp from Dragon's Eyes = 96 sp
+ 6 haste from socket bonus met
3 * 9 sp (9 sp from the two orange and 1 purple gem each) = 27 sp
2 * 8 haste (from 2 orange reckless gems) = 16 haste
Net gain in sp = 96 - 27 = 69 sp
Net loss in haste = 6 - 16 = -10 haste
69 sp * 1.31 dps per point in sp = 90.4 dps
10 haste * 1.22 dps per point in haste = 12.2 dps
Net gain in dps = 90.4 - 12.2 = 78.2 dps
TL;DR: I get more dps from JC than the tailoring cloak as it stands right now. I've heard a lot of talk about new gems, but so far all I've seen is the data mined shots of a gem that is unique which wouldn't affect JC at all.
*edit* forgot I was able to swap in a red gem for a purple gem in my extra belt socket which nets an additional 10 sp (10sp * 1.31 dps per sp = 13.1 dps). The total gain in dps for JC with this adjustment is 91.3 instead of 78.2.
