I believe there is 3 stages

Stage 1, a single person states something, gets no attention so they ignore.
Stage 2, 500 people agree on the single persons statement, it gets brought to developers
Stage 3, they will reply based on situation, currently they busy with battle system, dungeons, companies and cannot really apply ideas until after.

So do I think they care? At first, No. After interest, Yes. (They have to, not much of a choice).
