Asking people in a progression game to stop and hope that everyone else also stops to convey a message is a pretty hopeless optimist approach. People will willingly slog through unpleasant things to get what they want.
The part that hurt the most was people actually considered the part where we were forced to socialize as the content was so repetitive and boring (to the point I actually got carpal tunnel flare up because I did my rotation so much) as a PLUS. Like we love that the content is so mind numbing that the players stuck in the zone resorted to IRC level chatting to pass the time.
If they need it said, I'll say it again: Just because people are doing content, doesn't mean it's good. At best it means you locked something people want behind it. Remove the carrot and see who keeps playing it "for fun".
I left FF11 because of the death punishments, party reliance, and stress of traversing the overworld (and because at the time race/job combos mattered and I'd picked one nobody wanted). As you might guess, I wasn't thrilled to see that follow me into this game.
