They did listen, thats why they havent added new world spawns in a long time and changed kings. It's not how I would of liked it, but they did try at least.
This would be cool, but theyd need a way to only give the survey to people who had a level 75 job before the first abyssea expansion came out, that way only the people who participated in endgame/refused to participate during the years HNMs mattered could be counted for the survey. Newer players arent likely to know anything about how it was and would skew the survey.
