so what are the best builds, assuming two things. one, max surv needed is 120 (like airships) and then either range to hit up more places, speed to do places faster (no retri), or high retri for assumed farming of the massive amount of kamacite ore (that will probably come from sub nodes)?

note: need 3 ore per plate and 9 plates per part (or 108 ore for one sub and 432 ore for all four subs)

also note: I think its dumb as hell to add a new building materia that could take months for you to build your subs when there are only months left before 5.0, when subs will become trash, much like airships did when 4.0 dropped :/
