Quoted for truth.
Mine isn't a direct answer to OP's question, but I try to avoid repetitive farming as much as possible. I guess you could call me a credit-card farmer instead. When the gold <-- --> $USD exchange rate is single digit cents per gp, my time is far too costly to do repetitive 'work' for like a dollar an hour.
Granted, I don't really play the fashion endgame meta, so map-currency specific skins and such don't appeal. The only grindy nonsense I endure are meaningful upgrades like mounts.
Even so, huge respect to the map meta/farm experts out there. It's fun to very occasionally tag along.
