Nerfing sparks and unity enchanges for gil is not the answer.

Not everyone wants to spend their limited playtime on gil making endeavors. They would like to actually be doing events with friends.

Gil making/farming is part of almost every single game in this genre. There aren't many games out there where you can NPC a load of items that you just bought from another NPC standing 15ft away.
I seriously doubt people do stuff with friends ALL the time, so outside of that, is time to farm and make weapons. Otherwise, what else are you going to do?

Gil making/farming is part of almost every single game in this genre.

I mean, it is, but the games don't usually directly revolve around it, you just make money by doing the contents of the game, not by explicitly grinding out money with no other purpose in mind.

Until Sparks came along, this was mostly true of FFXI as well, since the game gave out almost no gil by fighting regular enemies with few exceptions.
