I agree with Riku.

You're forgetting about the +3% from having Aegis Assault up

All for One tactical is better than the One for All unless you're consistently hitting 5 or more people (which even in Operations can be a rarity based on which fight you're on). For Alacrity, your target in capped content (Anything that is NOT Dxun or Meridian) is based on your preference: Without the +5% Guild Buff 1815 - 10% Build (4211 Crit Remaining) 3207 - 1.3s GCD (2976 Crit Remaining) With the +5% Guild Buff 1895 - 1.3s GCD (4281 Crit Remaining) Personally, I just run 1895. If you're in Guild Buff content you get the 1.3s GCD, if you're in non-buff content you get the 10% build and it's simpler than continuously swapping sets.

Agree with the above. My sheet shows how to hit the GCD thresholds because that is what a lot of people had interest in. It shows certain alt-builds with those thresholds in mind. However, due to the nature of trying to keep it concise I didn't that ridiculous amount of build options that happen between the 1.4s and 1.3s GCD. The way to read the sheet properly is "this is how you reach the threshold in the most efficient way" but if you want to go over that threshold for other reasons it also gives you the most remaining stat to work with as well. 1.4s GCD is accomplished over 7%, but a lot of heavy-cast rotations do well with 10% (which is under the ~15% you need for 1.3s GCD). Basically use my sheet as a starting point, and adjust do what works beat for you!

You do have wasted stat in your "without wasted stat" builds though.

http://www.swtor.com/community/showthread.php?p=9805679#post9805679 You'll have to convert to Republic terms, but everything you need for PvE is in there.

For Mods, there are only 80, 80A, and 80B. Then there are the R-1 through R-20 variants. Enhancements don't have letter variants, they are just named differently followed by 80, and 80 R-1 through R-20 variants.

I believe you're mixing your terms. For Armorings, Tanks want Resistive 80/80 R-1. These give +431 Mastery, +451 Endurance. DPS/Healers use Versatile 80/80 R-1, which give +471 Mastery, +409 Endurance. For Mods, Tanks use Warding 80B/80B R-1. These give you +409 Endurance, +285 Defense. DPS/Healers use the Lethal 80 R-2's, unlettered.

I've been constantly checking my logs after I run ops and I haven't run into the Warding bug in a couple weeks now. So I would say it has been fixed? But I could just be getting really lucky timing with its procs.

"by far the best" is a bit of a stretch. In PvP I could see this being the case, but if you need that much CDR on Enraged Defense in Operations or Flashpoints then your healers just suck. I have actually stopped taking the -30s CD Utility for Enraged Defense because almost every time I got to press the button for it my healer has already put me above threshold and I can't use it. That being said, I do agree that it being from Kai and not being seen one time since 6.0 launched is absolutely ridiculous. Though if they were to work on anything regarding Tacticals/Set Bonuses, I would like to see them balance the current ones by buffing all the ones that undisputedly suck to actually make gearing an elective choice instead of super-obvious BiS sets.

Alacrity and Accuracy have caps because there is a clear target. Accuracy is about getting to 110% (PvE), Alacrity is about GCD thresholds because the community discovered it doesn't actually affect the GCD as advertised, it only counts once you cross the amount needed to reduce it by a full 0.1s. Because there are clearly defined goals, you can then use the formulas to give you clearly defined amounts. Tanks just have "take as little damage as possible", so there is no threshold for stopping a particular stat. It becomes about which stat gives you more of what you need in that slot. Defense being oversaturated means when you get to the Augment level you're getting so little of a return in comparison to Shield or Absorb that it isn't worth. Shield vs. Absorb is the same way. There is not definable threshold, it is just which gives you more in a given slot. You can do total stat efficiency, but that only tells part of the story. Each class has their own passive buffs to Shield/Absorb (and Defense) so you will stray away from total efficiency in favor of what makes the class work better. However, in doing this the diminishing returns will be the curb of how far away from efficiency you will go. Again, there is no definable threshold. It's all about Stat vs. Stat, compared to Acc/Alac which is "get to this point then stop".

That is definitely old considering it is about 258's. (Also can we talk about how they spelled it defenCe for some reason?). Currently on my Juggernaut I run 3501 Shield and 3010 Absorb (PvE), Assassin I run 3138 / 3373, and Powertech I run 4375 / 2136. As someone else said, in PvP stats have completely different priorities.

Given that 1 Enhancement gives you +409 of either of those, and that the BiS Ear/Implant gives +471, the short answer is "no". I am extremely curious to hear where you found that metric though!

In writing this I was trying to balance brevity and preciseness. There is a lot of math I left out because I know the average reader will zone out once they see equations and such (also why I paraphrased some of the passives down to what is relevant instead of just copy/pasting them). If you want more specific details I'd be happy to answer them here, and I will think about how to add them into the main guide.
