FFXIV survey questionaries

[Jeeqbit]

The last large scale survey they did was near the end of 1.0.
And even then the most requested stuff took a backend to what they wanted to implement first.

You say large-scale, but the population of the game probably wasn't nearly as big as it is now. There have been ones even within the last few years that are probably bigger just because of the size of the community now.

when? i've been playing this a long time and never saw any, even inputting "ffxiv questionarie" on search doesnt show anything

They have emailed them to random samples of players. I received one addressed to subscribed veteran players from Square Enix directly (not their usual marketing/PR addresses which probably can't tell if you are subscribed) and a lot of people on these forums said they did too. I've seen one mentioned that I didn't get recently. SE has also talked about surveys they did in live letters that informed their change of direction to make the MSQ work solo with trusts.
