A partial answer to the general topic :
Q: Why did you choose Namae-san for the dev panel?

A: When planning fan fest, I tell each region to think about it themselves. For example, in Japan, an extremely high percentage of players are raiders, so there's a really good response to battle development panels. Even if we talk about really specific, hardcore stuff, they understand what we're talking about. North America also has a strong raid community, so it's battles everywhere. On the other hand, Europe is very artsy, and everyone has different ways of enjoying the game, so if we focus on battles too much then the audience doesn't really get it.

So it seems there was no battle content questions in the FanFest because we Europeans are too busy with Glamour and Housing...
I was actually raging during all that Q&A session, although the Art panel was very good, it's such a missed opportunity to talk about something else than those annoying questions about glamour that we get EVERYTIME.
Still, following what Yoshi-P is saying, maybe we'll get more questions about this in Tokyo Fan Fest
