With the new version and particularly the armor penetration changes, I've made some interesting discoveries.
The following setups exclude Thalassian Ranger Gauntlets (extremely marginal dps increase, but hard to acquire), Thori'dal (slight dps increase, but also hard to acquire), ring enchants (not everyone has access to them, but it's not like they would have any effect on other gearing setup), and Hard Khorium Choker (actually a great dps increase, but not everyone is JC).
Assumed buffs/consumables are fairly maxed, with Imp FF, FI, TSA, and Imp EA not used; the latter would actually make for another investigation, as the soft ArP cap drops significantly--I imagine there will be interesting results, but I'll look into it later.
There are two sets--best setup with Fists, 6200 and 7700, and best setup with Glaives, 6200 and 7700. The main purpose of this is to figure out what changes one should make between fighting a 7700 and a 6200, and all deliberation after these links discusses the 6200 setup (or changes from the 7700 to the 6200), even if not stated. This is because the 7700 best setup is rather solidly set in stone, seeing as the 7700 ArP soft cap is unreachable currently, but the 6200 best setup is not (prior to this investigation, at least), since this spreadsheet modeled ArP beyond soft cap incorrectly prior to this latest release.
Here are the setups (in this spreadsheet):
Fists 7700
Fists 6200
Glaives 7700
Glaives 6200
I've been awestruck that there is so little difference between the best setup for a 7700 boss and the one for a 6200 boss, despite having some ArP well over the soft cap. I expected that some non-ArP alternatives would be better, but in all cases but one, they are worse.
In the case of the Fists setup, you wouldn't change one item going from a 7700 boss to a 6200 boss. Every possible alternative is a dps decrease. The best actual solution is to have a second Hand of the Deceiver enchanted with Mongoose, resulting in 15 more dps.
As for Glaives, going from 7700 to 6200 is almost the same case. Due to the MH Glaive having 21 hit, you can swap SS Ring with Hard Khorium Band, and this is the only such swap that yields more dps (and doesn't take you below the hit soft cap like this same swap would with the Fists setup). Seeing as you can't get a second MH Glaive, you wouldn't be able to Mongoose it (not only is it unique, but that would still be really impractical if it weren't; there are other people, you know! :p). Also, by some dumb stroke of luck, this 6200 Glaive setup yields exactly 1337 ArP, which is
awesome, and almost exactly at the soft ArP cap, depending on whether bosses are 6185 or 6200 (1335 and 1350 caps, respectively). I read about the former some time ago but I'm not sure which it is; not that it really matters, though.
Glaives is obviously also the better setup for both cases, but not all of us are lucky enough to get them :<
(Edit) Imp EA info:
It seems that enabling Imp EA has no effect on the above gear setups. In the case of fists, having a second Mongoose'd MH remains the best choice, and similar to Glaives with no EA being right around soft cap, this gets you just 99 (84 if they're really 6185) over the hard cap, so you'd be at 0 armor against a 6200 boss at all times :o. For Glaives, the same ring swap is the only thing you can do to increase dps.
So, thanks for this change to the sheet, Land (granted it's modeling correctly :p); it's been very insightful. And hopefully this post has been useful and informative to you all. Feel free to point out if I've made any errors :p
(Edit) In the 6200 Fists sheet, I forgot to change the MH enchant to Mongoose
