When I offer a free complete home instance for plundering in map or guild chat today I often get no response. Or a whisper like "sry, farming this or that gets more money in the same time". Maybe two years ago, I had to port in several times. With a growing number of home instance nodes the required time for a complete harvest grew. With falling crafting material prices (not complaining about them) the return dropped. Considering the hefty investment + time-gating I feel a home instance gathering turn should still be attractive and beat Silverwaste or Cursed Shore grind, which can be done in length, in terms of return per time. An NPC at the entrance handing over the harvest could do that. It should work for guest, though, MMOs are not least about the social aspect. I'd buy such an NPC.
