If you are talking about the same survey I’m thinking about, there is two things you need to consider there before making that claim.
First, is that the survey asked more about each specific individual change that went through. So, there are people that dislike the rework as a whole, but is ok with some aspects of the rework. Eg, I myself am not found of the rework, but I like the new turrets (after they actually raised its damage/slow), and I think the ultimate have potential to be awesome.
Second, that the same survey was sent to the main sub, and that survey was a lot more positive than the one that collected responses from the Symmetra mains sub.
Third, that this survey was sent before we were able to test them out on the PTR. It was mostly a popularity contest with the description only. Many things changed between Geoff’s talking about the rework, and what we have on PTR right now. Eg, we were promised a “large and thick beam”, which is why so many people agree with the changes. I can guarantee no one was expecting a two feet increase in range, and requiring Zarya level of aiming (people were expecting Moira-level of aiming).
