I think the big thing Yoshida wants feedback on is the gender change, as it's a bit of a taboo topic. If they approve this decision then it's going to open the door to a lot of other things. One maybe being same-sex in game marriages.

I personally am not going to change my character much if any. I personally would like to have the option later down the road of going through the story of the other Grand Companies though, like how you could switch between nations in FF11. I don't care about having to do the work all over. I just want to see the story involved with the other two nations if they differ greatly going forward.
