I don't think the team for FFXIV even works that way. The best way to explain is I feel SE makes content and decisions and it's up to us to enjoy it. If we don't enjoy it, we are not "doing it correctly" or we "can play other games". I don't feel like digging out sources but both of these statements have been made by SE when confronted with negative feedback.

A poll would only be useful for a team that is relying on player feedback to make decisions. I imagine FFXIV has to be worse off as a game for SE to even consider that sort of thing. They are doing fine just releasing whatever they want to see in the game. We're all still here paying while we complain.
