I think our best bet for getting a direct answer here will to be through Reddit. At both of the big US events Yoshi P attended this year, Pax East and Fanfest, the reddit mods were granted an interview and they asked questions from users.

Here's a link from the PAX East interview: http://www.reddit.com/r/ffxiv/commen...ew_with_naoki/

Yoshi P does listen to questions asked directly to him, you might remember the video from London Fanfest of a fan asking about the Spriggan hat that she had done a lot of treasure maps looking to find. He said that because she had done so many maps they would add it as a map reward in a future patch. Likewise, a question about a coil mount led to the ADS mount.

Honestly our best bet here is the next time the reddit mods ask for questions for the next event, we have someone articulately ask the question and we all upvote/comment/make sure it gets a lot of attention.
