Today I cancelled my subscription

I think they give you a multiple choice survey when you cancel your subscription on the mog station iirc.

You're thinking of WoW.

SE offers no such survey, or if they do it's super barebones with no kind of text entry to explain yourself. I can't remember what it said the last time I unsubbed (game was unplayable) but I don't remember it being a detailed process. Pretty sure it was just "ok we took your credit card off, see ya."

Bear in mind too that a forum mod would have to sift through all these threads to gather up the reasons why people are leaving the game, then that all has to be translated and sent to Japan where it can be ignored in the order in which it was received.
