Not at a computer right now, but just a couple notes:
1. Khepri Bonnet and Jacket and Thundersoul for Rudra's, and possibly Khepri Kecks too, but I never compared it to Athos before. TA Rudra's where?
2. More often than not, a second Vulcan's pearl on Mercy, and unless perfect augments on Hecatomb, Khepri Bonnet for SA. Khepri Kecks > Abatteur. And, as I believe someone mentioned, Wanion > Prosilio on SA. Unless perfect augments on Hecatomb Cap, Thaumas Hat for TA, followed closely by Nemetona.
3. Completely left out Pugiunculus, which is often the best offhand after 99 Twash.
4. Might want to mention that STR Thochka is usually better offhand than 90 Twash unless you tend towards lower end content (i.e. capping fStr and attack).
5. I've not seen any results that make me consider Skadi Chausses +1 for TP. However, Khepri Kecks are better than Thaumas unless you need accuracy.
6. SA and TA sets should not neglect multi-attack and haste gear. Sure, the single attack may do more damage, but it is not worth the overall loss of dps. Off the top of my head, I'd use Skadi's Head +1 or Oce+1, Epona's and Brutal for both sets, possibly Twilight depending on haste levels. To generate ideal sets on DPS, don't focus on damage but round damage (or whatever the second field is on dps spreadsheet, can't remember off the top of my head). Also worth mentioning that since there is no reason to use either of these solo outside of trying to stack TH, you may want to equip Assassin's Armlets +2 and Raider's Poulaines +2 in both sets as well (if you're forsaking WS damage for TH, another 100 damage isn't going to hurt).
7. Use is limited, but may want to include evasion and evasion hybrid sets.
8. Regen set. May seem trivial, but especially in places like Salvage and Dynamis, it will save you time/mp/TP.
9. Although I think you should include an ideal Evis, I'd suggest recommending gear based on Abyssea buffs. You may want to also include a normal Evis and an unstacked Mercy set for those who may not have the space to merit Exen. Unstacked Mercy can come within a good 100-200 of Exen sets and could also theoretically be worth using for aftermath.
10. For Your low end TP set, Nom Mittens followed by Raider's Armlets +2 should be better than Dusk. Athos Boots are also worth suggesting.
Also, damn you beat me to it ;3 Serves me right for taking so long writing up a guide. I think there are a few things you are missing that I can send you when I get back to my computer Sunday, but all I can think of right now is explanation of THF's role in Legion, because I've seen so many THFs mess this up and it can cause a lot of wasted time.
