@ZorokiHanuke Not to mention, a survey can be designed to instantly give the devs the feedback they want. I'd imagine it would likely be multiple choice or a scale of agreement/disagreement rather than actual text, as to avoid needing people to translate things. Such a survey could be immediately checked upon by the devs in Japan whenever they wish and wouldn't have to go through a translation process like Support Tickets or Forum feedback.
Fate/Grand Order actually does a survey every year around the game's anniversary to gather valuable feedback. Despite having some of the worst gacha rates on the market, it does incredibly well, being one of the most popular gacha games to date, no small in how they know they only made it this far due to the fans (they had a really rough first year) and how much they take into account fan feedback. So I know how well a survey can work. They even give out rewards for taking the time to do it, as to incentivize people into completing it.
