I'm part way through it now, and so far I'm just rating each feat on what is basically a 7-point scale, with the mid-point inappropriately named "slightly satisfied" - the mid-point should be neutral, otherwise the survey is skewing respondents to favor things.
I don't think you should have to spend an ASI on a feat to get a proficiency, and I told them as much.
There's a lot of feats I've never chosen for a character because they have features that are very hit-or-miss, and I feel weird blowing an ASI on something that might be helpful sometimes.
