Okay, so I've hopefully managed to update my formula in the spreadsheet.
Now, I still need to get it up to date by adding the last few new items and all in there (Hopefully still tonight, tomorrow at latest), but I thought I'd share some interesting things.
Remember, the spreadsheet operates under the same "scoring system" as the old High-Level Accessories guide. Regardless of how actually valid that way of quantifying the items is, here's some interesting stuff due to the defensive changes.
Fierce Dragonlord Helm is back on top after years of losing to the legendary Dark Noble Helm, and the Petrified DragonLion's Noble Head (Which was under previous standards the "best" option due to having massive MPM). Some of the newer good helms like Roly Poly Fishhead, Smashed Potatoes, The Glory of Twilly and others that followed the same stat format are now among the top due to their high BPD alongside other respectable stats.
Basically nothing changed in Capes, as Nick's Toasty Cape will reign supreme, probably for at least the next 2 years still.
In Necklaces, due to the buff of BPD, Unhallowed DeathKnight Amulet/Zeclem's Heirloom increased their dominance, and nothing is even close to them. However, the far away second spot is now inhabited by Linked Bands of Nature's Bounty due to the ridiculous 20 BPD.
With Rings, again Unhallowed/Zeclem stay on top.
At Belts, Voidwoven Belt stays at the top, with Werewolf Fang Belt appearing in second spot, followed by Defender's Dragon Belt.
Looking at these, there definitely were some nice changes there, I guess. While I went through these, I realized I should note that I only adjusted the values for the defensive stats. Crit is arguably weaker now, in which case LUK is nerfed by proxy (But also buffed by being able to increase Crit effectiveness), and WIS increases healing. All these are a lot harder to quantify, so I left them as is.
