Just a note for farming the current vision world - not all the FFX NVs have the same droprate bonus, which some others may have also not realised.

All of the NV bases as well as NVA Wakka/Seymour have the full 300% base bonus ( 20/50/100% for EX levels) but NVA SP Tidus and Jecht only have 50% base bonus, so even at EX3 give a much lower bonus than any of the others at any EX level. Also, NV Olive and NVA Rubicante/Barbariccia have a higher base bonus at 100%, so will match Tidus/Jecht EX3 at EX2 and match EX2 at EX0.

Hopefully this might help some people who just threw all their highest EX level FFX units onto the grind team like me squeeze a bit of extra bonus out, or open up some easier farm options with the inclusion of Olive.
