Any order of importance on upgrades? I know hands can pretty much be upgraded right away; but haven't rly kept up with much else since I left.
You could probably use an Acc back option, Letalis or Anchoret's. Atheling will still beat both with capped Acc, but there are a lot of situations these days where you're not capped even with buffs: Delve bosses, Difficult+ SKCNM, new AA/Zilart fights...
FWIW, if you want Anchoret's and aren't lucky enough to get the drop (JSE capes can drop randomly from any WKR, and from Colonization/Lair reives in Marjami, Yorcia, Kamihr, and Woh/Dho Gates), rumor has it that S-E is adding a 3:1 trade in program in March update or later - seems like it's in the works from some not entirely definitive JP dev comments. Basically just like Abyssea NQ Empy feet, trade in 3 capes for any job to get 1 of your choosing. So don't toss capes for jobs you don't care about.
Especially if you already have decent progress toward 100% Rank 3 Sauromugue Meebles, that's a really good thing to prioritize finishing up so you can buy Letalis. If you've completely ignored Meebles, yeah, could be annoying to get help on your boss wins or certain Rank 3 goals.
