So I saw this post on another thread and it left me speechless. Would anyone care to elaborate on this alleged buff to Tailoring?

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:

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.

Also rememeber if you're still casting while you run (Abar/HS Pyro/LB/even Fireblast) then you're losing no (or less) damage then if you're running w/o casting.

I'm curious why people model running as a chance to lose proctime. It could as well work in your favour. If you're moving when the proc is on CD, you're actually gaining dps than if you're moving with a static enchant on.

Here's a another way to explain it. Say you have to move 5 seconds every minute. (random number). You could lose 5 seconds of the proc once in a while. But you could also very well only move when it's on CD and cannot proc. If you had a 23 haste on your cloak instead, you would allways lose the small dps it brings whenever you're moving those 5 seconds.

So to put it simple, don't model moving as a negative thing for the proc, it would very well work in your favour as well, when comparing to the 23 haste enchant. It might be a bit more random than the 23 haste, but it averages out to exactly the same % lost over time.

Well, that is a good point, but something to consider which lessens the value of this is that most heavy dps burns, whether it be for the full duration of a boss fight (Patchwerk) or simply during a phase (Tenebron on Sarth +3) take place with relatively little movement. While this could be enough to make the overall dps a bit higher, the dps gain is still RNG dependant. Personally, if I know two changes will both each give me a relatively equal dps gain, I'll go for the static dps gain over a chance on proc gain any day.

Either way, from a pure min/max perspective, it currently looks as though tailor/JC will be the biggest dps gain unless something changes. If you've only room to pick up one (and thus are settling for less than a pure min/max), then the difference in dps gain is pretty slight and other factors such as profitability, ease of leveling, etc. should be taken into account as the deciding factors.

Crit rate: 350 - 51.90%
Hit rate: 213 - 15.12%
Haste: 649
Casting Speed: 1.374
Arcane Damage: 2911.6
DPS: 6024.38

Using 2.1.9, the listed buffs and listed gear, I ended with the above numbers. What could be throwing things off? Perhaps there was an update to the mage module that corrected something? I am as certain as I can be that I set everything the same way you listed. Almost a 200 dps difference.

Without seeing you rawr xml files, best guesses:

1. You are using Gemmed Wand and he is using Fading Glow (Accounts for hit and haste differences)
2. You forgot flask (Accounts for the ~125 SP gap)

Take a look at the other trinkets and relics floating around on wowhead/mmo-champ. Same stats as previous items, they're pretty obvious placeholders. Armour pieces also have placeholder graphics. Hopefully, there'll be another round of polish on caster gear stats too - the plate gear is spammed with +hit, so there's still hope for a general gear revision!

I very much doubt that they'll add proc items with different proc chances or cooldowns. 10% proc and 45s ICD has become the de-facto standard, making it not too difficult to compare items. If they messed with that again, it would become a new mess, to say the least.

So the 'optimal' arcane gear now uses the 4/5 Arcane Stability spec? Is it better to spec this way in the long run?

Just curious because I think I hit all BIS arcane gear last night, but I keep seeing you guys list Boots of Impetuous Ideals in your gear makeups.

Note that most of the quoted optimal sets assume that you are Horde which needs another 26 points of hit. That's why Boots of Impetuous Ideals are often recommended.

I won't be updating the main page until 3.1 hits live servers. The items listed have consistently shown to be best in slot when taken into proper consideration (other gear, consumables, raid buffs), throughout various releases of Rawr (from 2.6 to 2.2). Furthermore, there are so many variants of sets that are close, it's not worth reflecting them all. The number of things that could be causing one person to get higher (or lower) numbers than another person is daunting, especially when it's within a range of 5-10 DPS.

I've done my best to use one of the most accurate tools available and provide the results for others. I'll do the same with 3.1, when final mage changes are in. At that time, I suspect Rawr will be updated, and there will be many more items to take into consideration as well.

One of the interesting aspects I'm looking forward to is sorting out previously unused items. For instance, if a chest piece from Ulduar is a substantial DPS increase, enough so to lose 4-piece set bonus (excluding T8 set bonus), then an item like [Leggings of the Wanton Spellcaster] would clearly be superior to [Valorous Frostfire Leggings]. Although the goal of this thread (but more realistically, the goal of the first post) is to answer the question, "Is item A better than item B?" under "best of best" terms, that doesn't mean discussion of transition items cannot take place.
