There is nothing to farm in this game of merrit. There is no market to milk.

About the only use I can see for it would be to mine two gold ore nodes at once but you can do that with alt characters. Just log your miner alts out on a node. Then when its time to mine it, log them in, mine it, log out, log in next one, mine it again.

In ffxi it was great because you could dual box a rdm and a tank and kill just about any NM in the open world. You could farm anything too.

There are no NM's in FFXIV and anything worth farming at all is worth 100gil at most and adding a 2nd character isn't going to speed it up any, I can clear all the mob camps in this game before they respawn by myself so no point.
