I'm sure they absolutely read here after seeing a thread pop up about how the graphics update might affect dark-skinned characters, and then later seeing them address those concerns on stage at Tokyo FanFest. Also walking back on some planned VPR changes after the DPS section get spammed with requests to not ease up on positionals (granted they ended up removing the debuff, but whatever). I think they're just kinda picky about what feedback they find worth addressing for better or for worse.
