Next to a public test server for jobs and skills I really wish they have a place where they will show their ideas to some of the content before finalizing on it. I am not sure if Diadem or LoV would exist in that way if people would have been able to give their opinion about it before they had truly created it. I know its probably too much work and not that easy since you have lots of different views but a girl can dream, right?

(In one french interview they were asked about a vote after the end of a dungeon run. Like how they liked it and more, but Yoshida said that this would break immersion for the player so they will not do it, also they already have their data..really with all the things that exist ingame I am quite sure that there is enough to break immersion..heck you could just make this something that you do after your first run so people would not have to click it away every time.)
