(First and foremost, thanks for adding the Fury explanation and excising Concentrate from the Archer list, FFM.)
What a team building guide even entail, though? I'm asking this because a stringent one kind of gives people the ideal that they're ideas are automatically limited rather than testing them out and it being without a somewhat stable format would be kind of pointless.
The best thing I could think of be to inform people what the AI prioritizes and how to go from there. That may just be me, though.
For the record, I also don't think that the AUP and MAUP thing is necessary since the formulas are already there.
As for what I think needs to be added, they should probably be a line under Items to tell/remind (newer) people that Longbows are the only Indirect weapons. Similarly, you might want to mark what physical techniques, if any, are Indirect. Other than that (and realizing that Kikuichimoji has no room to say that it's Linear), all I'm seeing "problem"-wise are typo-related or arguable changes about abilities.
EDIT: Oh, and the Status Effect part is down now. (Also, Crystal was misspelled the first time around.)
EDIT II: As something of a compromise to what CT5Holy wanted, it would probably benefit a bit to say which weapons benefit from Attack UP/are physical and which ones benefit from Magic Attack UP/are magical for those are less aware or are forgetful or are unsure. I know that one person, at least, accidentally ended up using Two Swords Flails with PA Save, which effectively was a waste of a reaction slot.
Similarly, it would be beneficial to put a few reminders about Jump's odd qualities, such as not being affected by Martial Arts despite being physical and being elementally neutral regardless of the weapons that's used (unless you fixed that with the sword skill elemental carryover thing). That's all I can think of at present.
