To answer my own question, either Hunter/Archers or Beastmaster. Hunters are just a class I don't feel have transitioned well within the series proper though they do fair a bit better in the Tactics series, but even then I feel they are one-note (FFT) or they were diluted into too many classes that can't really stand on their own (FFTA). I've also just never been terribly fond of archery.

Beastmasters are a pickle for me cause frankly I do find them useful, but I feel like their only real use outside of a few very specific scenarios is to simply make acquiring all those useful Blue Mage skills easier on the player and once that's done, you never have to use them again. So they never feel like a class that is useful on their own.
