Can you truly be certain that Square Enix doesn't do surveys? It's a standard practice for companies usually.

I received one in the past, referencing my account and subscription information, showing it was directly from the developers and not a marketing team like usual. Some others on these forums said they received it as well at the time.

A problem with surveys is that, just because everyone is in favor of something, doesn't mean it's a good idea and sometimes a game developer has to put their foot down and say players are wrong. It is up to the game developer to do a long train of thought that leads them to conclude this thing that everyone wants would ruin the game in the long term, because sometimes it might. Many players only think selfishly of what they want or don't consider the effect of a change long-term, or the various consequences on other players than themselves.

Personally, I prefer solutions that address everyone's concerns instead of just some people's. For example, with job complexity, just being able to switch between a simple or complex version might allow both sides to be happy.
